TEXT: The present paper has been read at the 9th Conference on Luminescence
(Crystal Phosphors). The author has studied the properties of copper-
activated glass as related to its composition, conditions of preparation,
copper concentration, and the action of ionizing radiations. The examina-
tion of activated phosphate-, borate-, and silicate glass of plain
composition has proved that in all types of glass, copper may be contained
in atomic, mono-, and bivalent phase. The absorption band with its
maximum within 800 -~" 880 mp could be related to the presence of bivalent
copper.by application of the paramagnetic resonance method. The passage
of copper to the monovalent phase under the action of reducing agents
leads to an attenuation and extinction of this band. At the same time,
2nminescence arises and is intensified under the action of ultraviolet rays.

Luminescence of copper-activated glass
S/048/61/025/004/040/048
B117/B209
An absorption maximum in the region of 250 mg is characteristic of the
presence of monovalent copper in glass. This maximum comes into being
during the reduction of copper through carbon or ammonium fluoride. A
further reduction leads to atomic copper. This is indicated by the
formation of colloidal particles giving the glass a red color. The
position of the emission band m'aximum, when changing from phosphate to
borate and silicate glass, ic connected with a considerable intensifica-
tion of the interaction of activator and medium. These results are in
agreement with those obtained in earlier studies on glass containing
cerium. An increased concentration of the principal oxides and of
copper in glass promotes the passage of copper to the bivalent phase.
The luminescence spectrum also depends to a considerable extent on the
wavelength of the exciting radiation. Special analyses have shown that
the luminescence spectrum of glass with Sn, but without Cu, differs from
that of glass with Cu and Sn. An excitation of glass of the latter type
in the range of 254 mp leads to an energy emission in the short-wave
range with the maximum at 440 mp (blue luminescence), and an excitation
in the range of 365 mg to an emission at 580 MP (yellow luminescence).
In the above-mentioned spectral ranges, these glass types may be used

as indicators. The absolute luminescence quantum yield depends on the
composition of the glass, on the wavelength of the exciting light, and on
the copper concentration, In some cases, the maximum yield attains 50%.
When silicate glass with copper is excited by a radiation with A.< 250 mg,
fluorescence as well as afterglow can be observed. In glass containing
copper, an intense luminescence may be caused not only by excitation
through ultraviolet but also through Ionizing radiation. Studies have
shown that it is possible to produce glass screens with a luminescent
layer of a thickness of about 100 -, 200 p by means of the diffusion
method. In the discussion on the present paper, I. B. Keyrim-Markus
pointed out that the author's data to some extent also agree with data
of his own studies. He also added that, according to his data, the
luminescence spectrum depends not only on the type of glass (silicate
or phosphate) but also on its composition. Glasses with monovalent ions
(K, 'Na) show luminescence in the blue range, glasses with bivalent ions
(Cap Sr, Mgp Zn, etco) in the red range. This may probably be due to the
Cu'l- ions in the neighborhood of the ions mentioned. Moreoverv he points
out that the intrinsic glow of glasses, which occurs at higher temperature,
r
is quenched when copper is introduced. 1-Abstracter's note: Essentially

TEXT: The electrical, optical and paramagnetic properties of Fe 20 3 con-
taining glasses were studied in dependence on the composition and on the
redox conditions of melting. A total of 15 different compositions were in-f
vostigated, most of them contained SiO, and BaO or PbO. Electricpl con-
ductivity, the e.p.r. spectra and the spectra of optical absorption were
measured. log?- f(l/T) were straight lines, almost equally ascending.for
all glasses; log ? decreases with increasing-Fe 0 percentage. The in-
2 3
crease in conductivity is accompanied by a slight reduction of activation
energy. A comparison of glasses melted under different redox condition
shows that increased reduction (increased content of carbon hi the mass)
raises the resistivity irrespective of raised Fe II content* The eop.r.

spectra were measured in fields of up to 6 koe. Resonance lines were ob-
served at g-factors of 4.3 and 2.0; their intensity depended on the composi-
tion. If the carbon content is increased the o.p.r. lines fade out due to
Fe3+~~ Fe 2+ transition; the Fe 2+ e.p.r. spectrum can be observed-.6nly at
helium temperatures. The line with g - 2.0 vanishes first. On-investi-
gating the optical absorption it was found that both in the base of BaO and
PbO content the blue transmissivity depends on the iron coficentration. Corr-
clusions: The high conductivity of the glasses investigated is due to the
presence of Fe3+ ions (3d5) in octahedral configuration (coordination 6).

ABSTRACT: Despite the fact that there have been numerous investigations of ZnS-Mn
phosphors, adequate data are still lacking on the kinetics of the synthesis process
and on the formation of luminescence centers in phosphors of this type. The present
work was devoted to investigation of the kinetics of formation of Mn activated zinc
sulfide luminophors. There were studied the electron paramagnetic-resonance spectlu,
the luminescence spectra and the intensity of lukinescence under cathodic and ultra-
violet stimulation as a function of the activator concentration, the synthesis tem-
perature and the action of ionizing radiation. Mn activated ZnS phosphor is parti-
cularly suitable for investigAtion by the method of electron paramagnetic resonance

in lattice structure.,,,rhe specimens were prepared in
quartz tubes 3 mm in diameter. the Mn2+ concentration was varied in the range from
10-5 to S x 10-4 g/g; the heating temperature was varied in the range from 780..to
1200OC;*the heating time in the range from 5 to 30 min. The EPR and luminescence
spectra are reproduced in figures. In the range of low (10-5 g/g) Mn concentrations
the manganese luminescence spectrum does not undergo significant changes with varia-
tion in heating conditions, but at higher Mn concentrations significant alterations
are observed. These changes are attributed, on the basis of the experimental data,
to change from the,sphalerite to the wurtzite structure with increase of the heating
temperature. The experimental results indicate moreover, that the EPR method can be,
used for investigating the rate of formation of crystals, the character of the crys-
tals and the conditions of penetration of the activator into the crystal phosphor.

ABSTRACT: The authors make a detailed study of the absorption ispectra, luminescence, and

Luminescence was investigated in the region from 0.8 to 2P. It was found that the dura.ilon of
luminescence was the same in all emission bands: it did not depend on in which absorption

The appearance ofnumerous lines in the EPR spectra of irradiated boron anhydride is ex-

the asymmetry of the one starting center B03.1 The oxidation-reduction conditions affect the
structure of zinc-phosphate glass. The EPR spectrum for such glass made under oxidative
conditions Is similar to that for alkali-ph6sphate* glass. However, under reductive

ABSTRACT: The author reports a more-detailed Investigation of the ab-
sorption and luminescence spectra of dysprosium, making it possible to
.determine more accurately the pbsitions.of the terms.of the trivalent
dysprosium in glass. The glass was prepared in platinum and quartz
crucibles and contained between 0.1 to-10% of dysprosium by weight. The
luminescence was excited:witb mercury lamps at wavelengtbs.313,_ 365, 04,
and.436 nm. The Absorption spectrum consisted of weak bands in the
476, 456,450J. and,428 nm, and a few more intensebands in the
ultraviolet And infrared. 'Variation of, the dysprosium concentration in
the glass did not change,the,absorption.spe(,.trum or the luminescence

ABSTRACTS The mechanism of diffusion *f copper into the surface layers of glasses of
various compositions was studied by tho method of tinting by etching, or cementation,
in which copper diffuses into glass at a high temperature from a layer of paste depop-
ited on the glass. Copper sulfate# cELoridog and oxide were used in pastes containing
aluminum oxideq kaoUn, etc.9 and the luminescence induced in the glasses obtained by
ultraviolet light was investigated by imccessive removal of layers. In the glass,

idesp the diffusion of copper taken laace through exchange of alkali metal ions with
univalent copper ions. In silicate glasses containing an alkali metal wdde and alka-
line earth oxide,, the diffusion of ecipper occurs in the form of diffusion of divalent
copper into the vacancies of.alkalirmi earth elements. As the alkaline earth oxide
concentration rises and the radius of the alkaline earth ion approaches that of diva-
lent copperp the depth of penetration of the latter and luminescence intensity of the
glass increase. This diffusion is sharply reduced when silicate glasses are replaced
by borate and phosphate glasseng which do not become tinted and do not ImLinesce. IX

layer and a high resolving power are silicate glasses with a high zino or wSmalum

ABSTRACT: Studies were made on phosphate, silicate, and borate glasses of rather
simple composition with varying quantities of Tb and Dy. Concentrations of Tb ranged
from 1 to 10;%, of Dy from I to V, Absorption spectra were recorded on a Unicam. SP-
700 spectrophotometer. Luminescence spectra were obtained in the range 400 to 1000
ng at temperatures of 300 and 77K. Excitation was produced in tho regions of 365
and 404 m~L by a DRSh-250 mercury lamp. It was found that an increase in Tb content
in the glass led to a linear increase in.lumlneseence, but the duration of lumines-
cence did not depend on the concentration, attesting to reabsorption in the energy
transfer-from Dy to Th. It was found that an increase in Dy content diminished the
Card 1/2

average lifetime in the .5D3 state and greatly weakened the-ghort-wave band of lumines-i
cence. At the same time, a clear decrease in duration of luminescence in the 542 m~L~
band indicates that quenching develops at the 5D 4 level of Tb. An examination-ofthe
absorption spectra and of tho duration of luminescence of Tb and Dy shows that the
duration for Tb is substantially greater than that for Dy, but the molar coefficient
of absorption for Tb (484 and 489 m~L ) is a:bout half the value of the 472 mikband
for Dy. This means that energy transfer takes place both by radiation from Dy to Tb
and by nonradiative resonance from Tb to Dy., These results indicate that it is in-
possible to compute lowering of the threshold of excitation of the exciting radiation
in glass excited by Tb and Dy as compared with pure Tb glass. The authors express
their thanks to A. P. Abramov for his aid In the luminescent measurements. Orig. art.

Abstract In embryos with a crown-rump length of 13 mm there is as
yet no division into muscle layers in the mesenchymal
tongue rudiment. In the area at the bottom of the prima-
ry oral cavity, there appears a fan-like distribution of
columns of mesenchymal syncytial nuclei representing rudi-
ments of skeletal muscles of the tongue. The degree of
differentiation decreases toward the tip of the tongue.
In 25 = embryos myofibrils appear on the periphery of
the nuclear columns. Muscle tubules appear first in the

cable-like nerve fibers are already found in 13 mm ' embryos;
more or less distinct nerve endings in the tongue muscles
were revealed in 65 mm embryos. At first, being similar
to the cable-like structure of the nerve fibers, the motor
endings have a group character. With myelinization and
isolation of single nerve fibers, the appearance of isola-
ted motor endings accurs (120 mm embryos). This coincides
with the processes of further differentiation of muscle fi-
bers: muscle tubules become thicker and longer and a grea-
ter number of myofibrils appear. The muscle nuclei are
disDlaced from the center toward the periphery. The afore-
mentioned alterations are observed earlier in the skeletal
muscles than in the muscles of the tongue proper, a fact

ABSTRACT: Embryos and feti of all age groups beginning with a length
of 13 mm as well as new-borns in the postembryonic time were
investigated with a view to the problem mentioned in the
title.- In the 13 mm long embryo the tongue consists of two or one
mesenchym covered with epithelium. No signs of a differentia-
tion of a future muouous membrane can be found. The whole
epithelium consists of three layers, in some places of tio or onla!
layer. The whole surface of the tongue is still smooth. Hardly
noticeable bundles of primitive nerve fibers become visible
in its mechanism. The separation of the tongue into a future
muouous membran6 and a muscle layer can already be found with
a 20 mm long embryo. The mucuous membrane is covered by a
Card 1/4 two-layer epithelium. At the boundary of the mesenchym and the

epithelium there is a thin layer of argyrophilic fibers. The
author cannot accept the data by T. Hellman (Gellman)(Ref 1)
that the dorsal multilayer flat epitbelium formed in the
course of histogenesis was already multilayereL with the
16-30 mm. long embryo, and that it was two-laylTrAd*At the side.
According to the author's opinion the flat epithwelium. formed
during histogenesis forms the most differentiatedistage. In
the place, however, where the rapid process o7f new formation
of the papillae of the tongue (sosochki yazyka) takes place
the epithelium has not yet finished its differentiation. In
the course of the differentiation process single ciliated
cells (Fig 1) as well as wholegroups of such cells (Ref 3)
(they were found only with grown-up people) are formed at a
certain stage of the embryonic development under the surface
epithelium cells of the dorsal and lateral surface of the
tongue. During the histogenesis of the epithelium of the back
of the tongue concentric parathyroid glands (epithelial pearls
according to Schaff - in this paper called Shaffer, Ref 4) ale
formed. When they become larger they sink into the connective
Card 2/4 tissue below them and are grown around by nerve fibers (]Fig 2).

Its Innervation in the Course of Embryogenesis in Man
The formation of the groove-like (zhelobovatyye) and leaf-
shaped (listovidnyye) papillae (sosochki) takes place in
113-120 mm long embryos, while around the papillae grooves
and fissures are formed. At about this stage the mushroom-
like papillae (gribovidnyye sosochki) are sufficiently
developed. The thread-like papillae remain smaller during the
embryonic period. They acquire a thread-shape only in the
post-embryonic period. The differentiation of the epithelial
cells and their re-formation to gustatory papillae (wkusovyye
lukovitsy) takes place in 65 mm long embryos, i.e. earlier
than the three last mentioned types of papillae. There is
reason to believe (Refs 5, 6) that this takes place under
the influence of some nerve impulses. The 90 mm long embryo
(age: 12 weeks) has already deglutiti3n reflexes and begins
to swallow the amniotic fluid (Ref "l). The especially
interesting innervation of the mucuous membrane of the
tongue during the embryonic and postembryonic period is
described in detail. A considerable part of the complex
rezeptory endings in the mucuous membrane of the human tongue

ABSTRACT: In the volcanic center of the Dzhermuk Highland "Muraslar"
volcanic glass has been found in the form of sinter, kidney-
shaped or drop-like. The glass has a characteristic brilliance
and is either light- or dark green; it takes on odd, tubular
forms, varying in diameter from 0-5 to 2 cm, not exceeding
10 - 15 cm in length. At times the glass shows up as blots on
the surface of agglutinated strataq measuring 5 - 6 cm in dia-
meter. In this case, the cooling glass has taken the shape of
a drop, set in a funnel-shaped recess with the adjoining rock
being of a similar glass like substance, which shows that in
contact with the glass the oxidized rock has changed its color
to light gray down to a depth of 2 - 3 mm from the fringe of
Card the glass. The author is of the opinion that certain con-

ditions tend to indicate that these formations are not of vol-
canic origin, but due to fulgurite development, which is also
born out by the fact that glass sinters are only to be found
on high points, which are characterized by intensive development
of burnt crust on the flow of effusive lava /_ see also "cru't
ful-urites" (Korkovyye fuligurity) by G.K. GabrJyelyan-7.
