TITLE: Effect of uniform compression on the spectral characteristics
of phosphors
PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheakaya,
v. 25, no. 3, 1961, 366-368
TEXT: This paper was read at the Ninth Conference on Luminescence
(Crystal Phosphors) held in Kiyev from June 20 to June 25, 1960. The
effect of uniform compression on the spectral characteristics of alkali
halide crystals activated by copper and manganese was investigated. Fig.
shows the spectra of phosphors activated by copper at a pressure of I
and 6,000 atm. It is seen that at a pressure of 6,000 atm the bands
are shifted in the direction of short wavelengths. The shift amounts
to 0.6 + 0-005 ev compared to latm and increases linearly with pressure.
Under a-imilar conditions, phosphors activated by manganese show a shift
of the band in the direction of larger wavelengths. Thus, on KC1-Mnj Pb
under 4,700 atm pressure a shift of the emission band by 0.015 ev was

observed in the direction of larger wavelengths. The explanation of the
shift in the direction of shorter wavelengths in the emission bands of
phosphors activated by copper, mercury, and similar ions is that the
pressure causes a redistribution of luminescence centers in the excited
states. The theory of Johnson and Williams is discussed in this connec-
tion. All the phosphors investigated by the authors are set up in a series
according to the behavior of their spectral characteristics. The conclu-
sion is drawn that the distance between the ions in the luminescence
centers of phosphors with the same activator differs considerably less
than the corresponding lattice constants do. Thus, the structure of the
centers is determined by its activator ions. It is shown further that
the excitation spectrum of ZnS-Cu phosphor is shifted by 0.03 ev in the
direction of shorter wavelengths at a pressure of 6,000 atm. This is con-
nected with the increase of the forbidden band width occurring due to
the decrease in the distance between the ions. There are I figure and
6 references: 5 Soviet-bloc and 1 non-Soviet-bloc. The reference to the
English-language publication reads as follows: Johnson P., Williams F.,
Phys. Rev., 1j, 69 (1954).

TEXT; This is a continuation of previous work on alkali
halides by the same authors and is devoted to a study of pressure
stimulated displacement of the emission spectra of ZnS activated
by Cu, Ag, Au, Mn and Eu. For pressures u,p to 6000 atm the
emission bands of ZnS, ZnS-Cu, ZnS-Ag and ZnS-Au are displaced to
shorter wavelengths. In the case of Zn this displacement is
o.o65 (� 0.005) CV, and for ZnS-Cu (10-t g/g eq ) it is 0.0045
(� 0.005) Ev, i.e. 11 x 10-6 eV/atm and 8 x 10-~ eV/atm,
respectively. Similarly the displacement for ZnS-Ag and ZnS-Au
at 6000 atm is 0.035 (1 0-005) and 0.03 (1 0-005) eV respectively.
With ZnS-Mn and ZnS-Eu the displacement at 6000 atm is 0.02
(i 0.005) eV to the longwavelength side. The dependence of

where I P'x /I p9max and IPolk /I Po'max are the intensities for a
wavelength X at a pressure p and at-atmospheric pressure
related to the intensity at the band maximum at these pressures.
A possible mechanism for these shifts is discussed, based on the
characteristics of the electron transitions, the distribution of
impurity centres and their interaction with-the surrounding medium.

ABSTRACT: The authors note that the question of the origin of the emission bands of
ZnS base phosphors remains quite unclear. For luminescence centers corresponding to
the same emission bands, different models are proposed by different authors. Certain
hypotheses are discussed. In the authors' previous work (A. 1. Layaaar, Ya. Ya. Kira,
Trudy* IFA AN ESSR, no. 18, 23, 1962), the effect of high pressure on a large number of
zinc sulfide phosphors was analyzed. A particular study was made of the ZnS-Cu phosphor
(1. 10-4 g/g), which has a green emission band, and of non-activated zinc sulfide with Its
blue luminescence. This paper reports on the results of an Investigation of the effect of
pressure on the blue band of the ZnS-Cu. phosphor (1. 4. 10-4 g/g). The uperimental

technique was discussed in the work referred to above. The authors provide a new augu-
ment in favor of the vLew that the origin of these bands (that is, in the ZnS-Cu phosphor
and in the non-activated zinc sulfide) Is different. It is also established that the shift
in the emission bands of ZnS-base phosphors, caused by doping them with small amounts
of cadmium sulfide,- is the result, In the main, of the deformation of the US lattice by
the cadmium ions. "7he authors express their sincere gratitude to Doctor G. Ortman
(H. Ortmann), at whose personal suggestion the present work was carried out. 11 Orig.

TITLE: The effect of pressure on the emission spectra of fluorite crystals activated with

ABSTRACT: The author notes that the trivalent rare-earth ions, possessing the elect 'ror,
configuration Is 2.,.4fk5s25p6, in addition to a broadband structure, manifest a llne.Lil
(or narrowband) structure in crystals for the absorption and emission spectra. In a num-
ber of previous works, the author studied effect of high pressure on the electron- ribra-
tion transitions in different luminescence conters and e8tablished certain characteristic
peculiarities of this phenomenon. In the present paper, he has undertaken to investigate
the effect of hydrostatic pressure on the electron emission spectra of CaF,2 crystals,
activated with various rare-earth tons. A pressure of 6, 000 atmospheres was applied to
Card 1/2

'some emission lines of CaF2-Sm 3+ and CaF2-Eu 3+. It was established that in fluorite
activated with samarium, both of the investigated lines (at 15, 338 and 16,548 cm-1 are
shifted at 6000 kg/cm2 toward longer wavelengths; namely, by 6. 1 cm-1 and 6. 0 cm-1,
respectively. In europium-activated fluorite, on the other hand, the line at 15, 849 cm-1
shifts 3. 9 cm-1 to longer wavelengths, while the line at 16, 217 cm- shifts 3. 0 cm-1 to
shorter %-mvelengths, and the line at 17,436 cm-1 shows practically no detectable shift at
*all. There is a discussion of the possible mechanisms of the spectral shifts, connected
I with the intensification of the crystal field under the effect of pressure. "in conclusion,
the author expresses his deep gratitude to Ya. Ya. Kirs for proposing the subject of the
study and for supervising the Work to N. N. Kr!Btofell for his many, valuable remarks
during the discussion of the article, and to P. P. Feofilov for supplying the crystals.

TEXTs The authors studied the hydrodynamic and mechanical properties of
hybrid polymers on the basis of the selective solubility of one type of
blocks in the corresponding solvent to make a quantitative estimate of
the conformation changes of macromolecules dependent on the solvent, and
to measure the mechanical properties of the resulting films. They in-
vestigated 40 styrene - isoprene bulk copolymer (BCSI) made with butyl
lithium and consisting of four polystyrene (PS) and five polyisoprene
(PI) blocks. The molecular weight determined in methyl ethyl ketone was
M - 77,000, that of PS t M,;,&10,000, that of PIt U 5% 7500. Solvents
used were3 benzene, toluene, heptane, octane, and methyl ethyl ketone.
M mm thick films were obtained from 1 g1100 ml of solutions in heptane

sion coefficients were determined at 0-05% concentration by a Tsvetkov

Svedberg ultracentrifuge. The molecular weight was calculated according
to Svedbergs M - (S RT)/ [D(1.:7,)] (2), and Flory and Mandellkern,
2.5-10 N1 ( 1 tS ([I] /M2) 173] (3), where N - Avogadro-s number;
Q - density, and viscosity of the solvent. (3) presupposes conforma-
tion of statistical nodes of macromolecules, the linear dimensions being
proportional to M 1/2+6 (e - small parameter). The coincidence of
different mean weights in different solvents indicates weak polydispersty.
The absence of a relation between hL. and M~ and the mean hydrodynamic

recorded simultaneously, by means of the three-,-point automatic recorder KPP-09.
The softening points of the PVA and -L'ilms were 44 and 120C respectively. The
film bands were stretched at an elevated tempezuture, immobilized by clakos, and
rapidly cooled by a current of cold air. It was found that the diagrams-of

ABSTRACT: A study has been made of the preparation and physical and mechanical
properties of a polyimide, viz.; polypyromellitimide. j6st results showed that
the polymer may find widespread use as a heat resistantPand low temperature resistant
material, and is of special interest as a high temperature film dielectric. A poly-
pyromellitimide film similar to the U.S. H-film was prepared from pyromellitic an-

Polycondensation to the polyamido acid intermediate was carried out at 15C. Poly-
~yromellitimide films were prepared by drying solutions of the polyamido acid on
glass substrates at 20-40C followed by heat treatment at 80-400C to produce im-
idization. Optimum preparative conditions were determined. The films were trans-
parent, gold-brown in color, thermally stable, nonbU7ning at up to 600--!-700C, un-
affected by organic solvents, highly renistant to y- and UV radiation, low temper-
ature resistant, nonshrinking, resistant to humidity, and readily metalized'. In
its mechanical properties at high temperntureB, the material surpasses all existing
polymers. These properties can be further improved by orientation stretching, aftef
which they approach those of glass-reinforced plastics d metals. Orig. art. haai

ABSTRACT: The authors summarize the results of their earlier investigations of elec-
tron paramagnetic resoft~nce and luminescence of ~~ in NaCl crystals (Izv. AN SSSR
ser. fiz. Y. 29, 404, 1965 and preceding papers). While the authors' results con-
cerning the microstructure of the Mnt+ centers in NaCl crystals containing impurities
agreed in the main with those of others, they did observe a strong influence of cer-
tain cation impurities on the arrangement of the M& ions in the lattice. The pre-
sence of Cd++ and Ca++ as impurities violates the principle of local compensation of
the charge in such crystals, but the presence of F6+* does not. The strongest effect
on the microstructure of the )0+ centers is exerted by anion impurities, especially
r. The nature of the manganese -luminescence centers in NaC1 was investigated by
means of optical and EPR methods and it is concluded that in view of the observed

differences between the spectral parameters of the luminescence centers in regular
lattice points and those in clusters., that the results favor'the model of the
luminescence center proposed by F. Seitz (Trans. Farafty Soc. V. 35, 71~, 1939). The
net result of the research is that in quenched NaCl-Mn crystals the luminescence
centers are PIT& ions which replace cations of the main substance in regular lattice
points.. Admixtures of Cd4+ and Ca,++ ions exert a stronger influence on the distribu-
tion of the cation vacancies and increase the number of W&+ ions in a cubic environ-
ment. In crystals NaC1-MnF, the W& ions are predominatly localized near the F1
ions. In NaCl-MnCd crystals, the kinetics of the decay of the paramagnetic centers
changes strongly under I irpadiation., owing to the effective capture of carriers by
the Mn centers. Orig. art. has: 3 figures and 4 formulas.

ABSTRACT: Electron paramagnetic resonance is sed r studying the effect of gamma

radiation on paramagnetic manganese c NaCI-MnCI7-CdCI2 crystals. The work
was done to determine the qualitative changes in the local structure of impurity cen- i
ters during gamma radiation aind to develop methods for usirg electron paramagnetic re-'l
sonance in studying radiation effects. A spectrometer with rf modulation in the 9Gc I
range was used for measuring the-electron paramagnetic resonance spectra. The speci-
mens were irTadiated at room temperature. Curves are given for the kinetics of decay
under ordinary conditions and under the effect of gamma radiation. It was found that
the intensity of central lines is reduced4ore sharply by radiation than is the in-
tensity of edge lines corresponding to Mn v' + centers. The ratio of the number of

centers in the cubic surrounding N. to the centers with an associated vancy NV is ap-
proximately equal to:

ABSTRACT: This Author's Certificate introduces an instrument for determining leakage
in seals used for closing off an evacuated cavity. The installation contains an
assembly for producing a vacuum, a meter for measuring this vacuum, and a vacuum line
which connects the cavity showing leakage to the assembly for producing the vacuum.
The system is designed for quantitative determination of leakage into the evacuated
,cavity by using a tank with a condensation unit submerged in a liquefied neutral gas
land communicating with the vacuum line. Gas leakage through the seals is condensed
in this submerged uhit and the quantity is determined by chemical methods or by
weighing.

ABSTRACT: This is a presentation of the results of the investigation
of the geodimeter by Bergstrand, type NASM-2A. It was carried
out in 1957 by P. Ye. Lazanov, Scientific Worker of the
t'NIIGAiKtogether with B. N. Sosnovskiy, Graduate Student at
the TsIT.IIGAiK. This investigation was carried out simultane-
ously with the testing of the test model of the large optiCal
range meter of the TsNIIGAiK on the Sarata base net in the
Odeigshwa ob1,,zt 0 .This paper also includes information
concerning the results of a few investigations of Bergstrand
geodimeters which were carried out abroad (Ref 2, 3). The
geodimeter investigated in the USSR was obtained from Sweden
in August 1957. Summarizingly it is stated that with the help
of a geodimeter it is possible to measure a certain number
of triangle sides in first grade triangulation rows without
great difficulty and that hence an establishment of base nets

ABSTRACT: In 1958, Bergstrand's NTASM-2A geodimeter (Ref 1) was applied
to the measurement of bases and sides of the trian8iilation.
This work via:-, carried out by the bri,-ade of the Sredneaziats-
koye AGP (Central Asiatic Aerogeodetical Enterprise) under
the supervision of P. Ye. Lazanov, scientific coworker of
the TsNIIGAiK (Central Scientific Research Institute of
Geodesy, Aerial Surveying and Cartography). 2 trucks were
used. On lar,-e distances the geodimeter was carried by plane.
Surveys were carried out in the Kazakhskaya SSR (Kazakh SS10,
Gurlyevskaya oblast'(Gurlyev oblast') and Aktyubinskaya
oblzLst? (Aktyubinsk oblaot') from May 29 until Tfove,.iber 1.
It was an open area ;,,ith desert an(I semi-desert ve-Ptation.
Temperature varied between 0 and +250. On evaluation of
the corresponding data the rate of light propagation in
Card 1/3 vacuum was assumed to be 299792.5 km/sec. The jeodimeter

was fastened to signals or tripods. It was hoisted to the
signals by means of a s:-~all rope winch, which was mounted
on the truck. The procedure of survey is described in brief.
The results have ,!'hown 01,11t s11OUt the SILMO aCCurnCy Of

and invar wires. Experience h-.Ls shown thrit it ic Most use-
ful to measure distances of 15-20 km. The results of control
measurements of the bases by means of the jeodimeter car. be
used also for determination of the velocity of light pro--
pagation in vacuum. The values obtained -are very accurate
and are in accordance with those obtained by the British
National Lpboratory of Phy-ics in 1156 for the velocity
of the Prona-ation of radiolFaves (299792.5�0.1 kn/sec). in
addition, this result confi=s the v~tlue of light velocity
of 299792.~+O.4 km/sec, which was assurned by the XI General
Assembly of the international As.-.ociation of Geodesy. The
author gives the formula according to which the relative
errors of the measurement of triangulation sides .,,,ere cal-
culated. On the measure.-ent of distances by means of the
jeodimeter it must be taken into account that the meteoro-

the geodineter and reflector, do not represent these con-
ditions within the .,,rhole range of measurement. Furthermore,
the distribution of temperature, pressure and humidity can
be unequal throuchout the nijht. Each distance must be
measured during some nights in order to reduce these factors.
The results obtained by the investigations carried out
in the step2es of Central Asia have sho-an that within 2-3
days distances can be measured with a maximum error of
not exceeding 1:800000. This offers the possibility to
abandon the establishment of base nets andIthe survey of
bases by means of invar wires. There are 4'tables and 1
Soviet reference.

ABSTRACT: The authors undertook to investigate which wavelength requires the
determination of propagation velocity in order to gain the most reliable light
I telemetric measurements. Telemeter EOD-l with incandescent lamp STs-70 (known
spectral characteristic) as a light source was used to quantify a "working"
spectral bandwidth and effective light wavelongth. Preliminary calibrations were
performed to determine spectral diatribution or the energy of the light stream by
means of obtaining the spectral characteristics of sending and receiving systems,
the Kerr cell modulator, and reflector. A plot was made showing comparative
