The robability of the nonradiative two-phonon transition 7F - 7F0 of
SM 2V in the center of a cubic cell of F- ions in the fluorite iattice has
been calculated. From the probability of this transition, which takes place
during the operation of a four-level laser using a CaF2:Sm 2 * crystal, the
rate of transition of ions to the ground state after stimulated emission of
a photon with an energy of 14,118 cm -I can be ascertained. The calculated
value of W(7 F, - 7FO ) is 2.2 -10~O'sec- 1 at G*K and increases with increased
temperature. This confirms the assumption of W. Kaiser etaL that there is
no accumulation of Sm 2-o. ions at the 7F, level during the operatioA of the
CaF :Sm2 * laser. The calculation will allow a more ~rec'ise rendering of
2
equations describingo the operation of this laser. BB.)

-LEXT: Radiationless transitions between the energy levels of the active
impurity ions occur in lasers and irasers. It is assumed that
radiationless transitions are caused by the variable Coulomb fields of the
nearest neighbor ions. An interaction Hamiltonian (impurity ion - lattice
vibrations)'of the form H =,ZVQ, was used for the calculations. V, are
functions of the coordinat ed"'of the electrons in the unfilled shell. The
account for the potential energy of the impurity ion in the crystal
electric field. In this Hamil, -tonian only symmetrical oscillations
transforming according to the even representations r 3g and r59 have to be
taken into account. Experimental and theoretical results concerning the

ABSTRACT: The authors investiGated the widths and shifts of the absorption lines of
SrF, and BaF crystals, corresponding to phononless transitions
Gd3+ in CdF , CaF20 9 6P2
to Staek sU201evels of the terms 5/2 and bp 7/2 from the ground state 8S 7/2' as
functions of the concentration and temperature, Use was made of the energy levels of
Gd3+ in 'these crystals, corresponding to different symmetry centers, published by the
authors earlier (Opt. spektr. v. 20, 99, 1966; FrT v. 8, 142, 1966). rrhe Cd content
was 0.1, 0.3, and 1.0 at./'*. The absorption spectra were obtained with a diffraction
spectrograph (DIFS-8-1). The crystals were grown by crystallization from the melt.
The measurements were made in the interval 78--300K. All line widths increase with

ACC NR' AP6033572
increasing temperature in nearly linear fashion. The maxinum width range from 2 to
6 c=-1 at nitrogen and room temperatures, respectively. Line shifts occur with in-
I creasing temperature, amounting to 1-4 cm-1, at all wavelen6ths. '17he line width is
proportional to the Gd concentration. The widths and shifts increase with lowering
of the crystal symmetry. The basic metal does not affect the results much. A formula
is derived for the temperature dependence of the widths and shifts of cubic centers
in metallic fluoride and is found to explain the observed experimental data. Orig. i

TITLE: Parallel study of the photodielectric effect and the light
sum in ZnS-Cu, Co-phosphor
PERIODICAL. Fizika tverdogo tela, v. 3, no. 2, 1961t 575-577
TEXT: Among the great number of papers dealing with the photodielectric
effect, there are only a few concerned with a parallel study of the
optical characteristics of crystal phosphors. This ist however, required
in order to obtain a direct proof of the contribution of localized or
conduction electrons to t,.e photodielectric effect (phde). Tais has,
therefore, been the aim of tne work under consideration. The change of
the dielectric constant of the dielectric during attenuation of the after-
glow is described by the relation (1): log4~'t = log(-- 0 CO) -
log(i + W 202), where 6 0 and r-- Go are the c values for Oand',- co,
the relaxation time of phde. It may be seen from ( '1) that in
measurements at constant frequencies L-- is a function of the two

variables 0 00 and 1~ which in their turn change on the extinction
of the phosphor; as for -- it is known that it increases. The author
found that f' in ZnS-Cu. Co-DhosDhor rose from 4.10- 7 sec (durinR
excitation time) to 8.10- 4 sec (after extinction over 12 hours); during
the same time, E decreased by 11-51'. The reduction of 6E during
0 OD
extinction is thus above all due to a shift of the dispersion region
toward low frequencies. Most authors believe that the presence of a
phde at nitrogen temperatures ~s indicative of the contribution of
localized electrons to the phde; however, also a change of frequency
- might explain this fact. The author was able to observe the effect,
at room temperature, of the "freezing in" of phde on ZnS-Cu, Co-phosphor
at a certain frequency (conservation of the phde over hours), whereas
a rapid drop was observable at other frequencies. Owing to the fact
that a parallelism in the change '- -. and the change of the light sum
would be a direct proof of the participation of localized electrons on
phde, the author wanted to find out whether such existed. He used the
method of the circle diagram by Cole (J. Chem. PhYs-, 9, 341, 1941) for

the purpose. The diagrams were drawn at 200C during excitation and at
various moments of de-excitation, and in parallel thereto, the curves
of thermal de-excitation, immediately after excitation was over, and at
various moments of de-excitation, likewise at 200C. The results showed
that such a parallelism does not exist; the phde is thus in the main
caused by conduction electrons; the same has been found by F. I.
Vergunas (FTT,.j, 2322, 1960), who supervised the work under consideration.

and w = oD, p0 the natural frequency of the localized electrons, and U
the height of the inner potential barrier on the localization levels,
or also simply the depth of the localization levels, To explain the
experimental data, the phosphor must be assu med to be a set of levels
with different values of U. It is therefore always possible to find a
temperature range in which the after-glow ca n be ascribed to levels of
one and the same depth. In this region, exp erimental data must be
described best by the theoretical formulas. Tr., this end, the author
studied the thermal de-excitation of ZnS-7,u, Co-pnosphor (,5.10_5 g CuIg,
10-6 g Co1g) and found this phosphor to nave four systemB of localization
levels. Excitation at room temperature 'Led to the population of the
localization levels with electrons, and the curves of thermal de-
excitation exhibit two peaks at 20 and 780C. The depths of tLe
localized levels were calculated after these curves; a depth of 0.5 ev
was obtained for the 200 peak. Log was fu rther found to be a linear
function of the logarithm of attenuation tim e t (G, rises with t after
a hyperbolic law). A verification of (2) is possible by measuring the

temperature dependence of G. The curves log 19 f(l/T) should be
straight lines, by the inclination of which it would be possible to
determine the level depth. Curves like the one shown in Fig. 21
however, and not straight lines, were found by the experiments. While
'I also in this case formula 1 describes the experimental conditions to
satisfaction, formula (2) cannot be put to good use. The author also
studied 'the change of the relaxation time of phde at nitrogen temperatures
and found that after excitation was over, 6 increased by more than one
order of magnitude, which again is not a point in favor of formula (2).
All the results are indicative of the fact that in ZnS-Cu, Co-phosphor,
phde is caused by conduction electrons. F. 1. Vergunas is thanked for
having supervised the work. There are 2 figures and 6 references:

formula (2) gives Q = --onst or even a slight decrease, since ~, decreases
during the extinction. According to Eq. 9 can rise during quenching
only when electrons escape from levels with lower U values, and the
effect of levels with higher U values consequently increases. It was
found that in spite of electron e;;cape from levels of equal depth, 9 in-
creases in contrast to Eq~ (2). Moreover, the variation of 9 during
quenching was found to obey a hyperbolic law. This is in accordance
with Eq. (1) and the results of Ref, 7 (F. I. Vergunas, Yu, L. Lukantsever,

Izv. AN SSSR, Ser. fiz., 11, 1294 (1959)) to the effect that the concentra-
tion of the free electrons which is proportional to photoconductivity
decreases during the quenching of the afterglow. Formula (2) may also
independently be checked by means of the temper.-."ure dependence of 9.
For this purpose, the phosphor which was exciteu at 20OCp was slowly
heated after long extinction (12 -. 14 hr). The center of the dispersion
range was observed to shift toward higher frequencies. Also in this case,
Eq. (1) is a good description of the variation of Q. Eq. (2), on the
other hand, gives no satisfactory description of the dependence of 0 on
the duration of afterglow and on temperature, even when local levels of
equal depth are occupied in the phosphor. The study of the relaxation
time of the photodielectric effect at liquid hydrogen temperature has
shown that formula (2) is not suited for the description of the variation
of 9, either. Thus, the results proved the conclusion of Ref. 1, namely,
that the photodielectric effect in ZnS-Cu,Co phosphor is due to conduction
electrons. The author thanks F. I, Vergunas for having supervised this
study. There are 4 figures and 7 references: 6 Soviet-bloc and

PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskaya,
v. 25, no. 4, 1961, 559-561
TEXT: The present paper has been read at the 9th Conference on Luminescence
(Crystal Phosphors). The author reported on a parallel investigation
of the photodielectric effect and of the light sum in ZnS-Cu,Co phosphor.
It was his aim to prove directly whether localized electrons or conduction
electrons participate in the photodielectric effect. Circular diagrams
of ZnS-Cu,Co phosphor were taken during excitation and during quenching
of the afterglow at 200C (Ref. 2: F. I. Vergunas, G. M. Malkin, Piz.
tverd. tela, v. 2,2322 (1960)). Simultaneously with these measurements,
the curves of thermal extinction immediately after stopping of the
excitation and during quenching were taken at 200C. The light sums stored
in the phosphor depending on the time of afterglow were planimetrically

determined from these curves. The author obtained the following data
which he compared with the values of the increase in capacitance in a
constant field:
Time of quenching, [hr] 0 1 2 12
Increase in static capacitance, ~pF] 56.5 50 50 50
Stored light sum, frelative unitd] 100 34 29 14.4
The light sum drops- to about 113 of its value during the first hour of
quenching. At the same time, the static capacitance decreases only
slightly. The number of trapped electrons decreases continuously. The
static capacitance remains constant. Thus it was found that in ZnS-Cu,Co
phosphor at room temperature the decrease of the light sum and W - W
0 OD
are not interrelated (') 0 and cj 00 denote the dielectric constant at the
frequencies &)= 0 and -.). co, respectively). This is in accordance with
the conclusion of Ref. 2, namely, that the photodielectric effect in the
phosphor concerned is chiefly due to conduction electrons. From this
viewpoint one can also explain the insignificant decrease of the static
capacitance during quenching, since this quantity quickly reaches
saturation, depending on the concentr,4-~ion of the conduction electrons.

Parallel investigation of the ... B117/B209
The concentration of conduction electrons contained during a permanent
afterglow in the phosphor is apparently sufficient for the saturation
of the static capacitance. The author thanks F. I. Vergunas for having
conducted this study. In the discussion to the present and to the
previous lecture (I, v. 25, no. 4, 556-559), Ya. A. Oksma'n pointed out
the fact that in spite of the numerous possibilities of photodielectric
methods, the latter are still too little used in the study of processes
in semiconductors. As far as the investigation of the photodielectric
effect is concerned, new information on the properties of localized and
free charges can be obtained only after formal methods of investigation
have been developed, and after an analysis of experimental results has
been completed. The method of considering the polarization field, which
was suggested by Felitsiana Ignatlyevna Vergunas, appears to be interest-
ing from this viewpoint, since with it a more detailed study of the
distribution of the space charge may be avoided. As to the specimens,
single crystals appear to be more suitable than powders. There a.L,e
