TEXT: The formation of F centers in monocrystalline layers of the KI
(Tl) phosphor has been studied in detail., It was.found that the accumu-
lation of light energy exhibits three different mechanisms, depending
on the excitation energy: an electron-hole, an-exciton.., and a "delo-
mechanism (RZhKhim, 1960, no. 9, 33849), all of which lead to
the formation of F centers. The luminescence of-KI(TI) during excitation
has also been studied. The steady luminescence consists of two compo-
nents, i. e., a llrapid11.1~p (fluorescent lifetime shorter than I see and
a "recombinative" one (fluorescent lifetime of the order of 1 min.. An

radically from sensitized PhOGDhorescanco of organic molecules (Ref 11)

anion excitons and at A = 186 n~a it generated free electrons and

lue in less than 1 sec from,beginning of excitation and a "slow"
~component which reached the steady state in about 1 min. The fast
component exhibited no optical quenching (it was unaffected by F-
band illumination), but it was quenched thermally at 500 - 6000K.
It was, thereforeq concluded that the fast component represen.ted
"direct" excitation of activator ions. The slow component was
quenched thermally at 250 - 3500K, indicating typical external
quenching of recombination luminescence. P-band illumination Q,

band traneitions, but the slow component was.enhanced when ultra-
violet excitation generated excitons. A simile theory, accounting
for the observed quenching and enhancement of the slow component,
is given in the paper. Acknowledgment is made to Ch. B. 1jushchik

TITLE: Mechanism of the processes of energy accumulation by crystal
phosphors
PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, v. 25,
no. 1, 1961, 23-27
TEXT: The present paper deals with the following mechanisms of energy
accumulation by crystal phosphors: production mechanism of F-centers'in
crystals, and mechanisms of thermal and optical "de-excitation" of ion
crystals. Three stages are distinguished in energy accumulation by
crystals: 1) production of a long-lived excited state; 2) long-lasting
conservation of the excited state; 3) processes.of"de-excitation" of the
~6tybtal. D. I. Blokhintsev (Ref. 1) showed that the electrons and holes
occurring after excitation are localized at lattice defects which are far
from one another. For this reason, their direct recombination is
impossible, an~i the electrons or holes must be set free from the trapping
~centers for "de-excitationil of the crystal.. Intense ion diffusion prevents

the crystal from remaining in the excited state for a long time. Even in
the production of the simplest 'F-centers it is necessary to take account of
both the active role of electron - hole processes and exciton, sensitizing,
ion processes, etc. The number, nP of F-centers can be concluded either
from the absorption XF_ n., from the intensity of luminescence photo-
stimulated in Che F-region, or from the electron emission photo-stimulated
from the F-centers. The accuracy of the two last-montioned methods exceeds
the first by several orders of magnitude. Fig. 1 shovis the absorption
spectra (1) and the spectra of the production of F-centers (2) for the
phosphors KC1 - Ca, Tl;1KBr - Ga; KBr - In; and KBr - Tl. According to
the data obtained, the P 1 states of monovalent impurity ions can be
"de-localized" with a certain probability, which results in the formation
of F- and V-centers in the basic material of the crystal. Fig. 2 shows
the spectrum of the production of F-centers in KI - Tl as measured by the
luminescence method. F-centers are formed not only in the ac region but
also in the,ex (-220 m)u) and ep regions (-190 mp) with even stronger
efficiency. The production mechanisms of P-centers in the ex- and

ep~-regions differ from each other. The dislocation mechanism of the
production of F-centers'needs additional investigations. The authors then
discuss the mechanisms of thermal and optical de-dxcitation of ion crystals.
The'third stage of the phenomenon studied here has been investigated in
~'revious papers. The thermal destruction of F-centers in alkali-halide
crystals does not lead to their direct thermal ionization. For the NaCl,
icl, and Or crystals, the thermal destructIon of F-centers in the range
100-3000K is connected with hole processes'l in the range 400-5000K,
however, it is related to electron processes. The ultraviolet radiation at
the same frequencies (in the ex and ep regions) is capable of producing
and destroying F-centers. Finally, the authors demonstrate that alkali-
halide salts are typical crystal phosphors. During an investigation of the
luminescence of alkali-halide salts with excitation in the region of self-
gbsorption of the crystal it has been found that many phenomena observed
in these crystals are the same as in ZnS phosphors. This investigation
was carried out at Tartu. Further details on this subject will be
published later. This is the reproduction of a lecture read at the
Ninth Conference on Luminescence (Crystal Phosphors), Kiyev, June 20-25,

TEXT: This paper was read at the Ninth Conference on Luminescence
(crystal Phosphors) held in Kiyev from June 20 to 25, 1960. For a
general investigation of nonisothermal relaxation processest a so-called
"relaxation combine" was developed by the authors. With the help of this
combine, the curve of thermal decoloration K(T), thermal de-excitation
I(T), and thermo-optical det-excitation IX(T) of a crystal can be
simultaneously reoordedl and the "instantaneous efficiency of thermo-
luminescence" can also bd measured. The latter characteristic is do-

Here, I is the intensity of luminescence, and n the number of color
centers. The:experimerital determination of this characteristic requires
the simultaneous measurement of I(T) and k (T), since n mIT . These
quantities were determined for single crystals of KC1-Tl, Ur-Tl, and
NaCl-Tl irradiated with X-rays. The resul-,a are gzaphically represented
in'Fig. 1. -The curves are schematic. Curve 1 represents the thermal

Curve 3 represents the thermal de-excitatic.1 (with separation filter for

to differentelectron and hole states+of the relaxation process. At
the va rious staA;es, the value of Q(T) varies from 0 to co. The infinite
values are due to the circumstance that in the range of investigation the
~P-centers are not destroyed and the observed thermoluminescence coincides
with the decomposition process of other color centers. The vanishing of
Q(T) is related to the low effectiveness of energy transfer from the
recombination centers to the luminescence aenters~ and is usually obtained

ABSTRACT: The authors point out that, for the study of the mechanism of recombination
luminescence of cryi3talline phosphors, various optical. electrical and other methods are
in use, the majority of which fall Into one of two classes: 1) Study of the action of
radiation on excited or non-excited phosphors; 2) study of the relaxation characteristics
of the phosphors. Various techniques for the study of thern Ineecence are discussed
and their relati.'ve malts are analyzed. It Its noted that the study of thermoluminescence
cannot completely roplace meamements of "Integral" curves of thermal glow, since the

Important in a quantitative Investigation of the kinetics of the relaxation processes, to
difficult and time coimuming on the basis of measured spectra. In this article, which to a
continuation of the Investigation begun in a previous work (I. V. Yaek, M. F. M.
Trudy* IPA AN ESSR, no. 21, 96, 1962), the authors investigated the recombination
luminescence spectra of X-rayed KBr-phosphors. Thermal glow curves and thermo-
lumine~cence spectra of Tl+-, In+-, Ga+-, Sn2+- and Pb2+_ activated KBr were mea-
sured. . It was found thati the'thermoluminescence, spectra obtained coincide fairly well
with the activator fluorescence spectra. There Is a discussion of the limits of applic-
ability of the spectral investigation method of thermal glow. The thermoluminescence
characteristics of Sn2+- activated phosphors and those of in- and Ga-activated phosphors
were found to be sinillar. The hypothesis is advanced that this similarity is due to the
ability of SnZ+V+ceni;ers to capture both electrons and holes (V+ to a cation vacancy).
The reasons for the absence of thallium Ion emission during the low-tetnperature stages
of the relaxation process are discussed. "The auth 'ora express their gratitude to

ABSTRACT: The authors have extended the investigations of two of them (~J.F.Okk and
I.V.Yack, Izv. AN SSSR, Ser. Piz,, 299 46 (1965)) on photostimulated luminescence in
ionic crystals to.include stimulation by radiation on the short wavolongth side of
the F band. The luminescence excitation spectra of x-ray excited KCl!Tl crystals
were recorded at 300 and 1060 X for stimulating photon energies from 1.6~to 4 eV.
Four peaks were observed in the spectra: the F-band peak at 2.2 oV, thoIK-band peak
at 2.75 eV, the T10-band peak at 3.3 eVt and a peak of unknown origin at 3.8 cV. The
temperature dependenceuof the luminescence intensity for stimulation in the F, K, and
Tl0bands were separately recorded for the temperature range from 80 to 300 0 K. The

intensity of the F flush decreased monotonically with decreasing temperature; that of
the K flash was almost temperature independent; and tho intensity of the Tlo flanh
increased somewhat with decreasing temperature. The temperature independence of the
X-flash intensity in in good accord with the findings of H. Kanzaki, T.Ninomiya, and
K.Kido (J.Phys. Chem. Sol,, 22, 309 (1961)) on photostimulated conductivity. It is
concluded from the present results and different findings of other authors that the K
flash is recombination luminescence in 'which true optical (hot) electronp, rather than!
thermal electrons, partIicipate. The reason for the increase of the Tlo-flash intensity
with decreasing temperature is not known. The authors thank Ch.B.Lushchik for sug-

Ti- ions have*one and the samecharacter. However, the splitting of the
orbital triplet in the phosphate glasses is larger than in the silicate
glasses. In the iilicate glasses, the splitting is largest when the'

use of a tube ultrasonic generator, together with a P114:2(G412)

was polished. The fixing was carried out using a small tack. The
vibrator was enclosed in a steel cylinder and fastened to it by a
flange. Cooling the cylinder was effected by running water. The
acoustic head was protected from the vibrations of the chopper by
some sponge on -the upper part. At the lower end, the concentrator
end was soldered to the studied sample (brass wire of diameter
1 mm). The amplitude of the oscillations was measured with a mi-
croscope. After sounding and without unsoldering from the concen-
trator, the.sample was discharged at room temperature, The zounding
took place at 34 Kc/s at an amplitude of 0.0125 mm. Results of the
experiment are given. The ultrasonic oscillations cause a simulta-
neous decreat3e in toughness and plasticity of the brass; thus after
15 seconds of sounding the toughneca wan reduced by 9% and the re-
lative elongation decreased by 50%i when sounding lastod more tfiari
15 seconds, the sample was destroyed. Ultrasound causes a lowering
of all the characteristics of static toughness of brass and a de-
crease in the work needed to cause destruction of the sample.

practically unchanged..The suggestion is made that lowering the
toughness of brass-as a consequence of sounding is connected with
the transition of the metal in the stable state, and -the aimultan-
eous decrease in plaiticity, and with the shattering of the crystal
structure. The hypothesis is argued upon that the toughness of
brass decreases as a consequence of the lowering of temperature
with sounding time. 3 figures. 3 'Uables.-9 references, /'-Abstrac.-

by.means.of oxidation burning in a fluidized bed (FB). Weighed
portions (4 - 36 g)of AB, containing 85% of total B and 11% Mg,
were placed in a chamotte crucible and air was blown in through
the bottom of the crucible with a rate of 20 - 35 1/min, at a
temperature of 20 to 4000C, and a burning time of 30 - 95 minutes.
When.the reaction zone (RZ) of the furnace was heated up due to
the hot air, a thermal gradient of 120 - 11100C was observed over
