--Abstract - 1--A study of the absorption spectra bf leuco base dyesi Lauth's violet,
niethylene blue, thionine blue, capri blues green malachite, crystal violet,
etc., in solid state showed that the presence of gaseous hydrogen sulfide
results in the conversion of many solid dyes into an achromatic compound.
The rate of reaction of the dye was observed t-D be increasing with the in-
crease in temperature. Such achromatic compounds sublimate rapidly at tem-
peratures above 500C. The solid leuco base dyes regain their original color
when exposed to atmospheric air. Graph.

Title : About the photo-conductivity of colored organic films during il-lumination
with vioible light
.Periodical : Zhur. Fiz. Khim., 28, Ed. 5, 856 - 864, May 1954
Abstract : Exneriments to determine the photo-conductivity of colored collodion films
-during illumination with visible light brought only negative results.
Photo-conductivity could not be.revealed. The increase in electrical
conductivity during illumination odth visible light, as observed by many
researchers, is not due to the internal photo effect but to the heating of
the colored film as result of the absorption of the light energy in the
natural color absorption band. Arguments in favor of the electrolytical
nature of thn electrical corrfir~tivity of colored collodion films are pre-
sented. Fourteen references: 943SR, 2-Hungarian, 3-USA. Table, graphs.

Abstract: longer waves by 900-1,000 cm-1 and the short wave band of alcoholic
solutions of I# II and LB III reveal a weak oscillatory structure
which is $PseA in the solid films. In the LB the band 300 mu
constitutes a displaced band of phenyl groups of triphenyl methane,
while the band 260 mu is caused by the presence of dimethyl amino
groups and constitutes a band of the latter displaced from the far
ultraviolet region. In the dark on contact with air films of LB
of triphenylmethane dyes are stable; under light in the presence of
oxygen the dye is r*Prated but due to theittneurrent process of
photochemical oxidati;~ of the dye a complete coincidence is not
attained between absorption,Orves of pure dyes and dyes regenerated
from LB. AS of products of photochemical fading show characteri8-
tic absorption bands with a A(maw) of 358 mu in the case e.. I and
II, and 450 mu in the ca6e of III.

Title Nature of the Absorption Bands of Leuco-Bases of Thiazine
Dyes.
Orig Pub Optika i spektroskopiya, 1956, 1, No 4, 478-489
Abstract The absorption spectra of solid layers of leuco-bases of
thiazine dyes (thionene, methylene blue, azure 1, methy-
lene green GO, toluidene blue 0, thianine blue, and neo-
methylene blue), obtained by direct reduction of the solid
dye in an atmosphere of H2S at 100 -- 1700, were measured.
Comparison of the absorption spectra of the simple aromii,
tic amines of leuco-bases of triphenylmethane and thiazine
dyes has shown that the long-wave band with a maxinnim of
335 -- 338 millimicrons is due to absorption of the phenyl
group, vhile the bandwidth and maximum at 255 -- 268 mali-
microns is due to the amino group.

ABSTRACTs Investigations of electric and photoelectric properties of dyes
have shown that they can be considered as a class of organin
semiconductors,
Temperature-dependence of electroconductivity for many dyes
is described by the formulat
6. exp
where Er is activation energy, which has the following values
for various dyes: 2.28 for trypaflavins, 2.13 for eosine,
2.15 for erythrosine, 2.08 for phloxin, 1.8 for pinacyanol,
and 1.6 ay for phthalocyanin.
Photoconductivity-temperature dependence obeys also to an ex-
Card 112 ponential law, but the values of activation energies are

ABSTRACT The paper under review prosents the results of the investigations
of the photooonduotanoe of layers which are obtained by rubbing-on
of the powder of the violanthrone (dark blue indanthrene YO M)
and of the pyranthrone (golden-orange indenthrene G (?)). The
investigation was oarried out with the aid of an devSoe that had
already been described in an earlier paper. The layers (oPa thick-
ness of 0.1 to neiiMAIniorons) were applied to a 'quartz finger'
containing platinum electrodes. The photoconduotance was investiga-
te& in vacuum, although the presence of air does not affect the
results in any considerable way. A tungsten incandescent lamp
of 100 W was used as source of light, and the light was decomposed
by a mirror monochromator with vitreous optical system. The distri-
bution of energy with respeot to the wave lengthes was determined
by means of a thermoelectric pile. The current intensities of the
order of magnitude of lo-13 a were measured with the aid of a
direat-ourrent amplifier.

photoourrent becomes constant and then deacreases almost equally fast
if the exposure to light is terminated. If the obeeryation is car-
ried on for longer periods, an additional increase in the Dhoto-
current will be frequently noticed. If this long-period exposure to
light is suddenly terminated, the photocurrent first of all quiokly
deoreasesp but there always remains a remanent photocurrent which
decreases only slowly. The photocurrent obeys the Ohm's law,at l4aist
at field strengthes uP-to 4000 V/om. The dependence of the phots-
current It on the intensity L of the exposure to light Is described
by the mathematical relation it - & , with a and n denoting
constants. In the layers under investigationt n always remained
below 1 and amounted to 0.7 to 0.9, depending on the thickness of

the volt-auLpere dependencer. of the dark current and the photo-
electric current for a photoelectric cell of the type I with
pinacyanol. This dependence gives evidence of the existence of
a barrier lajer.The photoelectric current increases together
with the tension in the pass direction and tends towards a sat-
uration;in the barred direction it winks towardG nil.In the case
of a photoelectric cell of the type II the pass direction and
the barred direction change their parts as against the cells of
the type I and vice versa. A photoelectric cell of the type III
does not show any rectifying properties,the dark current at small
tensions responding to Ohm's law.Thi5 result confirms the lack
of a barrier layer. The here found results are also valid for
photoelectric cells with orthochromine T and with crystalline
violet, but they hardly agree v;ith the assumptions on the valve-
like nature of the photoelectromotoric power. There is no cau2a-
tive relation between photoelectromotaic power and barrier layer.
So far the iitructure of the barrier layer and the mechanism of
the rectifying at the contact dye- metal have not been explain-
ed. The photoelectromotorical power excluuively develops from

than that one obtained for the optic activation energy. It is ex-
pected that the conductivity of the Pt - Mg layer at the experi-
ments carried out here, was an impure one. In the presence of oxy-
gen the conductivity of the Ft - Cu-, Ft - Zn- and Ft - 111g, layers
increases. The sensitivity of the Ft - MC; layers in relation to the
oxygen is as great that a pressure of 0,1 mm of mercury is suffi-
cient to cause an essential increase of the clectroconductivity.
At room temperature ths electroconductivity of the layers treated
in oxygen at 150 - 200 C is almost by 1o4 1 105 tiLies Ureater than
in vacuum. At a temperature rise the conductivity increases ac-
cording to the law: i!r T exp(- E,/2kT). However, the value
E is essentially smal%r 1han the value FE , which was obtained
Card 2/4 in 1he vacuum. The value El depends on the oxygen pressure. The

behavior of phthalocyanine complexes in oxygen proves the occur-
rence of an impure conductivity. The increase of the activation
energy of Ft in oxygen is to be attributed to the increase of the
energy threshold at the boundaries between the microcrystals.
2.) Photoconductivity. An illumination by visible li~;ht of plitbalo-
cyanine layers carefully dcgassed with high isolation properties
causes an essential increase of the conductivity. The oxygen also
increases the photoconductivity. In layers with oxygen generally
does not form a space-charge. A noticeable retardation of the sta-
bilization of the steady photo-current and its decrease after stop-
ping the illumination is observed. The photoconductivity of the
layers with oxygen is essentially hi.-her, than that in vacuum. The
layers of phthalocyanine free from oxygen have an inertialess pho-
toconductivity. In this case the photoconductivity is linearly re-
lated to the intensity of illumination, and exponentially increases
at a temperature rise. Some repults point to the presence of tran-
sition resistances in the phthalocyanine layers which weru obtained
by the sublimation. Taking into consideration the essential in-

results in the determination of optical activation energy.
2) In thin layers the spectral curves -' the relative photo-
conductivity calculated by taking into account the non-lineari-,
ty of photoconductivity show good coincidence with the ab-
sorption etves. 3) The introduction of oxygen into the phthalo-
cyanine layer on the one hand essentially increases the total
photoelectric sensitivity, but on the other hand does not
exercize any essential influence on the spectral distribution
of photo-sensitivitY. 4) The A 1/2 method and the method
of the "photo-electric straight line" show close values for
the optical activation energy of the phthalocyanines when
thin layers are used and when the non-linearity of photo..
conductivity is taken into account, 5) The optical activa-
tion energies obtained for phthalooyanine without metal as
well as for copper- and zinc phthalocyanines well agree with
earlier determined thermal activation energies. 6) The re.,

found that to avoid overheating the initial, deposited from solution,
layer of a dye should, in general, be thin and uniform; only
rhodamine B layers should be iticic. It was not possible to obtain
an undecomposed layer of malachite green using the ca 11 shown in
Fig 1. Be;t results were produced by rapid sublimation. To check
that the sublimated layer is free from decomposition products the
authors measured absorption in the ultraviolet region which was
sensitive to impurities. 'the absorption spectra of sublimated layers

absorption by layers deposited from alcohol solutions. This difference
is the same in all the dyes considered; in the visible region the
sublimated layers absorb more strongly at longer xavolen&ths ttian do
the layers d6posited from solution. The converse is true for short
wavelengths in the visible range. The differences may be due to the fact
that the layers deposited from solutions are more continuous than those
prepared by sublimation. Moisture affects strongly the absorption spectra
of sublimated layers-, the absorption curves are different for sublimated
layers measured in vacua and those measured in air (a.-. Fig 3 curves 1:

measured in vacua differ also from the spectra of solutions. Tnis
difference is smallest in auramine 0 spectra, where only some broadening

ABSTRACT: As far as the authors know, the electric and photoelectric
properties of indiCo have hitherto not been investigated. The
present paper shovis that indigo possesses photoconductivity and
is a typical organic semiconductor. Indigo is nearly insoluble
in the usual readily volatile solvents. Therefore layers were
investigated which had been produced by sublimation of the dye
in a vacuum ("10-5mm) at a temperature of 130-1400 C. -2hese
layers were located on the surface of a quartz vessel upon
which platinum electrodes had previously been fitted. Amperages
were measured by means of a direct current amplifier, and the
light was monochromatized by means of a mirror monochromator
ISP-17A. The relative spectral distribution of the energy
inciding upon the layer was measured by means of a thermopile.

kBSTRACTt The aim of the present paper is that,of determining the electrons
'
either on an excited singlet level or on a
(which are situated
triplet levei) that cause electrical conductivity in the dark, that
is, in other words, whether the activation energy of eleotrioal con-
ductivity in the dark corresponds to the height of the triplet level
or of the excited singlet level. Reference is made to a new idea
advanced by A. N. Terenin (Ref 8) on the nature of photoconductivity.
The application of data concerning the phosphorescence of solutions
to the solid state is said to be unjustified. The objects investi-
gated here are supposed, on the one hand, to be phosphorescent in
the solid state, and on the other hand, the distance between the
triplet level and the excited singlet level is expected to be as
many times greater as possible compared to the error in measurement
6M (here - 0.1 ev). The investigation was therefore made on benzo-
Card 1/3 phenone, anthranilie acid, phenyl anthranylic acid, as well as on

3-acetYl,amine-N methyl phthalimide, 3-acetyl amine- X phenyl
phthalimide, and 3-benzoyl amine- N methyl phthalimide. Moreover,
the electrical conductivity of fluorescein as well as of some other
dyes was investigated. Sufficiently thick (- 50,A) and dense layers
were prepared by sublimation of the substance in high-vacuum
(^,10-5 mm). These layers were sublimated on the surface of a quartz
vessel. The voltage source was a dry-cell battery (560 v). In order
to be able to measure the absorption spectra, the layers were
applied to a quartz plate which, in turn, was fastened to a rotating
faceplate. The results of measuring the temperature dependence of
electrical conductivity are reproduced in figure 2. The wavelengths
corresponding to the thermal activation energies CL arein good agree-
ment with the longwave drops of the absorption curves. The totality
of the results obtained is indicative of the followingt Electrical
conductivity of the organic semiconductors investigated occurs an

TEXT: By way of introduction the authors discuss the results yielded by
investigatione,most of which were conducted by the authors themselves,
The result Is concern the photoconductivity of inorganic and organic semi--
conductors.4he formula derived by De Vore (Ref. 6) for the photocurrent
is given aTid discusned. This formula is regarded as being an expression
characterizing the change in the photocurrent on a variation of sample
thickness 1 at a determined wavelength of incident light. The authors
wanted to carry out a quantitative evaluation of De Vore's theory for
the surface recombination rate in linear photoconductors. They further
wanted to determine lifetime, diffusion coefficient, and mobility of the
photocurrent carrier. For this purpose, they examined variously thick

in vacuum. Fig. 1 shows the photocurrents as functions of the wavelength
of incident light along with the absorption relative to the two dyes
examined. Figs. 2 and 3 show the photocurrents as functions of the layer
thicknesses for three different wavelengths. With the aid of a -r-meter the
lifetime was found to be 1.1-10-4 see, and this quantity served for de-
termining the recombination rate on the surface and the carrier diffu-
sion coefficient. The values are tabulated in Table 1. The diffusion
coefficient, the recombination rate, and the carrier mobility of the
dyes examined were found to be smaller than those previously observed on tr
inorganic semiconductors. This is partly brought In connection with a
reflection effect caused by the smooth surface of the semiconductor. The
authora thank Ye. K. Putseyko and 1. A. Akimov for having supplied the
T-meter and for valuable advice given. There are 4 figures, 1 table, and

TEXT: The authors give the results of Investigating phototubes in air.
Under longitudinal illumination in air, one of the dye-layer contacts with the
electrodes is seen to give rise to a photo-emf, the sign and magnitude of which
are determined by the nature of the dye but which does not depend on the nazure
of the illuminated contact (push or natural contact). The photo-emf (Eoo)-and
short-circuiting current (I ) are assiciated with illumination intensity by the
relations E-- A 1n (1 + 1Z and Io - UP. Photosensitivity is observed in the
natural-absorption region of the dyes in the solid state. The rectifying proper-
ties of dye phototubes are caused by the presence of a barrier layer on the metal-
dye push contact, In contrast to Noddak and Meyer, the present authors found
that the appearance of photo-emf is not associated with the presence of a

PERIODICAL; Akademiya nauk SSSR. Doklady, v. 143, no. 6, 1962, 1317-1320
TEXT: The electrical conductivity and the spectral photoelectric
sensitivity of layers of blood pigments such as haematine,.heamine, and
haematoporphyrine were measured. The layers were prepared between
platinum electrodes on a quartz substrate and thoroughly outgassed,
haemine and haematine at a temperature of 140'C, haematoporphyrine at
1000C. The currents were measured with a 3MY-3 (alU-3) d-c amplifier with-
a set of input resistors up to 6.8-109 ohms. after the layers had been.
kept in the dark for a lonG period. In the photoelectric measurements the
direction of the illumination was perpendicular to the direction of the
electric field. Monochromatic light was supplied from a H(-TT-17A (ISP-17A)
mirror monochromator. For the determination of the optical activation
energy of photodonductivity a C-0-16 (SI-16) incandescent tungsten lamp
calibrated from the brightness temperature for 656 m1c was used. The

light intensity was controlled by means of blackened metallic Exids, The
dark current and photo-currents were found to follow Ohm's law up to field
strengths of 104 v/cm. In the investigated temperature intervals
(haematine 52 to 1550c, haemine 35-1400C, haematoporphyrine 35-1000C) the
conductivity a followed the law
6 - a.exp(-1T/2kT)
The values LT of the activation energy measured in vacuum (haematine
2.03 ev, haemine 1.85 ev, haematoporphyrine 2.07 ev) agree well with
values from absorption spectra. The corresponding wave lengths (609, 0667,
597 mm resp.) belong to parts of the absorption spectra corresponding to
sinElet-singlet transitions. `Uhen haematoporphyrine is heated to 1350C,
it is converted to protoporphyrine (activation energy 1.83 ev). The
activation energy of haematine is considerably lower than that of
haemoglobine (2.66 ev) which is thought to be determined mainly by its
-rotein content. In presence of oxygen (cf. Fig. 1)t the conductivity-
temperature-curve of haematine shows a peculiar form: Above 1100C oxygen
has no effect, but at lower temperatures the conductivity is considerably

enhanced by oxygen adsorption. The dependence of tho photo-current i phot
on the illumination intensity L was found to be of the form i ' aLn with
phot
n near to 1. For haematoporphyrine and haemine the temperature
dependence follows the law i i-exp(-6 AT) at 5-800C with
phot 0 phot
phot ~ 0.2 and 0.18 ev resp. For haematine, log i phot was not a linear
function of T_ 1 except between -30 and +300C where L phot ~ P.1 ev. The
spectral photoelectric sensitivity curves of haematoporphyrin and haemine
are similar to the optical absorption curves. From the experimental
results it is concluded that in-vacuum the investigated blood pigments are
intrinsic semiconductors. There are 1 table and 2 figures.

TEXT: Liyers of dyes are decolorized by reaction with hydrazine vapor
at room te 'mperature. There is evidence for a specific interaction,
different from the formation of a true leuco-base. If t-he hydrazine is
pumped out and the layer is heated to 600, or it the decolorized layer is
exposed to air, the original dye is quickly regenerated. This cycle can
be repeated many times. Unlike true'leuco-~ase's the undyed products are
in most' cases unstable intermolecular compounds, called quasi-leuco-bases..
The spectra of astraphloxin, aurin, hemine and hematine are shown in
figures together with those of their quasi-leuco-bases and the regenera-
U
tion products. The absorption spectra of the solid layers of colorless

similar to those of the leuco-base layers. They consist of two bands
whose maxima are bet%een 250-270 and 290-310 mg, respectively, depending
on the state of substitution in the end amino group. The spectra of the
4-
quasi-leuco-bases of rhodamine group dyes consist of three bands*at about
232-238, 265-276 and 302-317 mA,, respectively. Some of the rhodamines
can also be reversibly decolorized by vacuum heating or the action of "X"
gaseous 11 2S at room temperator.e. The bands of aurfn (268 nm) and its
quasi-leuco-base (281 nm) are close to those of phenol (270 nm) and the
phenolate ion (282 nm). In the interaction of hydrazine with aurin
fiuoreacin, and gallein, a reversible bathochronic shift is observed if
the hydrazine vapor pressure is low. Considering the ease with wh-4ch a
.number of dyes change and lose their color, one must assume that in the
.Anteraction with hydrazine the p'roton is only-partially drawn off by the
!hydrazine, or the electron is only partially attracted by the dye, just
enough for charge-redistribution in the electron shell of the dye molecule
which is characterisAic for an anion, i.e. a molecule wh1ch has lost a
proton, and for a reduc,ed dye, i.e. a molecule which has accepted an

Spectral distribution of B102/B186
''in a great many previous publications, it was again oboerved that there is
a tight correlation between the spectra of photoelectric sensitivity of the
deposited layers of chlorophyll and the optical absorption spectra of the
Pigment solutions. In all cases the bands were very broad. For the layer
the 673-mg band had a width of 850 am- for the solution this maximum is
~at 662 mg and has a width of 650.cm-1. The shift of the red maximum
amounts to 250 am-1. The presence of dry oxygen (250 mm Hg) in the ampule
raised the conductivity; the dark current remained weak. Illumination of
the absorption band with monochromatic light raised the conductivity by a
-factor of 101_102. Stationary photocurrent was reached after less than'
drop took 10-15 sea- these times are much shorter than those
4 sec, the
observed by Nelson (i.Chem.Phys�27,864,1957). The absorption spectrum.of
the layer proves to be red-Aifted with respect to that of the solution.
The absorption spectra compared for two layer thicknesses show a oonsider-,
able difference: whereas the blue bands correspond, this is not the case
for the red bands; there is a shift so that the thin layer has an absorp-
tion peak where the thick one haa a minimum. There is 1 figure.

TEXT: Amorphous layers of pure chlorophyll a obtained by precipitation
from concentrated pigment solutions were investigated in high vacuo and
in oxygen at temperatures not exceeding 700C. Detailed descriptions of the
experiments are eiven in a previous paper (DA110 1490 no. 3 (1963)). The
ff., of the photoconductivity was determined by
measuring the photocurrent set~up~in a layer by irradiating it with a
CVI -16 (SI-16) lamp at various tungsten band temperatures (1200-22000C).
Between 2200 and 16000C the nonlinearity index nT varies from 0-72 to 0-76,
and.betwoon 1600 and 12000 C n varies from 0-76 to 1.01. The thermal

ABSTRACT: A scheme of automatic control of thermal conditions of
oil-fired open hearth furnaces developed by the Central
Laboratory of Automation and installed on the Nr 10 furnace
of the above works is described. The scheme-~o.,Qarates accord-
ing to four programmes corresponding to four technological
periods of the smelting process. Programme 1 includes a
considerable part of the charging period and two thirds of
the melting period; it is switched on by a motor relay of
time, operated by photorelay during the tapping of steel.
Programme 2 includes the remaining part of the smelting
period; it is switched on by a motor relay of time operated
when a stable excess in the preset roof temperature is
attained. Programme 3 includes the refining period and is
switched on by a motor relay of time operated at the moment

and the beginning of the charging period of the next heat.
Changing of programmes can also be hand operated. The
scheme is shown in Fig.l. Fuel consumption is controlled
according to the timperatures of the roof and regenerators,
The following parameters are controlled: consumption of
fuel oill air-fuel ratio, amount of compressed air used in
the atomiser, pressure of gases in the furnace, reverses,
waste gas temperature at the bottom of the regenerators and
draught in the waste gas flue. Characteristic data on the
furnace on which the scheme was operated, operating prac-
tice and operating results are briefly described. The
scheme operated satisfactorily, but the final conclusion
regarding the efficiency of the scheme can be made only
after an analysis of operating results of a few furnace
campaigns. There are 9 figures.
