Title :Thermoemission and Thermoluminescence of Fluorite.
Orig Pub: Cs. cas. fYs. 1955, 5, No 1, 75-85
Abstract: Continuing previous works (Referat Zhur Fizika,
1956, 11659; 1957,
10342), a simultaneous measurement was made of the
tbermoelectronic
emission (TE) and thermoluminescence (TL) of natural
crystals of
CaF2 M, colored by X-ray exposure after discoloring at
900 0C. The
uncolored I does not display either TL or TE. The curves
for TE and
TL obtained upon uniform heating from 300 to
approximately 3r.00 K,
are similar. The peaks ATL ancl P*rT. on the TL cunre lie
at the same
temperatures, namely at 360 and 5656 respectively, The
Peak C

C lie between A and B). In the region between the peaks
ATL and
BTL the color of the thermoluminescence changez twice.
Re3ults
for X-ray exposed I are the saw as for I with natural
color! ng,.
Upon maintaining X-ray exposed I at 200, the peaks AT

decrease, while the peaks 'RPE and ATL increase. For. f,
0.-r'ok'd
to X-rays at -1860 C, one ob-derves two other peaks of0
thermolu-
minescence at approximately 100 and appro;xima-tely 200
K. On the
basis of the results obtained, and as well as results of
works
cited, it is concluded that the thermoelectronic
erassion and
thermoluminesconce are due to electrons liberated from
Une same
color centers, and therefore the energy of the
dissociation of
these centers can be determined from the
thermoelectronic emission
curves by a method analogous to the analysis of the
thermal-glow
curves for these phosphors. Thermoluminescence haa t"'to
components,
a biznolecular one and a monomolecular one. The work
function does
not affect the thermoelectronic emission, this being due
to the

larger velocity of the thermoelectrons liberated from
the color
centers. The peaks A, B and C are ascribed respectively
to the
F2-, F, and F2 centers. A band scheme for the process
is proposed.

Title: The Effect of Additives on the Color, Electron
Emission, and
Luminescence of X-Ray Irradiated Ionic Crystals
Original
Periodical: Ceskosl. casop fys., 1955, Vol 5, No 6 (also
published in German With
a Russian suamiary in Chechool. fiz. zh., 1956, Vol 6, No 2,
141-151)
Abstract: Single crystals of NaCl were drawn from a melt
containing additives,
the content of which was determined in the finished crystals
by the
polarographic method, apd was found to be as follows: Ag, 6
.10-4;
Ca, lo-3j and Pd,, 8-10-4. After irradiation with X-rays at
16-180 C
the crystals vere uniformly heated from 300 to 7000 K; during
heating
the thermal einission (TE) and thermal luminescence (TL)
curves were
recorded. The mature and concentration of the additives have
a con-
siderable effect on the fo tion of long-wave absorption bands

Abstract: (0- and N-centers with low ionization energies). The
TE and TL peak
at-3500 K is caused by M-centers and is observed in all cases,
while
the TE and TL peak at-5600 K is caused by the F-centers and
depends
to a great extent on the nature of the additives. The TE and TL
peak at 3500 F: disappears after standing at v180 C for 20
hours.
Contrary to the conclusions drawn by Hill and Schwade (Referat
Zhur -
KhimiYa, 1956, 18594)10), the author concludes that in addition
to the
F-centers there exist a whole series of localization levels in
the vi-
cinity of the conduction band which produce TE peaks. It is
estimated
that the thermal ionization energy of the F-center is equal to
1.25
and not 1.03 (IV (Referat Zhur - Khimiya, 1956, 1861o). It is
indicated
that TE and TL are independent processes each of which can
occur in
the absence of the other. Natural fluorspar was roasted in an
Fe-tube
in air at 940 C and rapidly cooled; after X-ray irradiation the
fluorapar exWbited a green color and emitted a sharp yellow TL.
When
the same treatment was applied to fluorspar using a quartz tube
a
violet color was observed together with a very weak TL. It is
con-
cluded that the green color was not due to the presence of rare
earths
but to some other additive.

Abstract To observe certain optical and electrical
phenomena
in CaF2 crystals, the authors have used a complex me-
thod, consisting of measuring two quantities that
characterize simultaneously the porucesses that take
place. One of these was always the integral thermo-
luminescence, while the other was either the thermo-
emission, or the thermal absorption, or the thermo-
luminescence as a function of the frequency. The
measurements ware carried out at a constant temperatu-
re or at a temperature that was gradu&Ily increasinG

various
crystals are quite different. In all the
investigated
crystals one can, by suitable heat treatment and
color-
ing, attain a situation whereby the principAi
maxJmwai of
thermally stimulated EE are located 370, 480 and
6500 K
(rate of heating 20/sec), and the corresponding
absorp-
tion bands are located near 5800 A and near 5200
and 3600
R. The curves of thermal discoloration have
qualitative-
ly the same appearance for all wave lengths in the
visiv
ble and the ultraviolet regions. This is due to the
strong overlap of the individual absorption bands
and
makes it impossible to employ the method of thermal
dis-
coloration for a mutual comparison of the maxim of
ther-
nially stimulated EE, TL, and absorption. In
crystals
colored by the combined method, only the first low
teiape-
rature maxima of TL and EE coincide (4400 K). The
EE has
another strong maximum at 6500 K, but the

ABSTRACT:
Open-tdr point counters respond to
crystal water (freed from

the sample) with maxima of the
counting rate. A sharp-pointed

counter with corona discharge
responds with streamers only to

not able any more to record single

however, possible to mea.sure the

"watex-glow-curves" in
analogy to the exo-elect-Ton glow

curves (1~3fs 2,.3,A). This
paper brings the results obtained

by means of another device

TEXT: The thermoemission (TE) and themoluminescence (TQ of
radiation-colorcd MgO and CaO powders
were measured to complement other optical and electrical
methods of investigation. TE and TL curves for
MgO (300'K to 800'K) and CaO (300'K to 700'K) show essentially
parallel behavior for each sample.
Periclasc single crystals containing some percents of iron
showed weaker TE and a TL curve differing from
that of MgO powder. The similar shape of TE and TL curves for
these oxides of not toobigh an electron
affinity show again that exoemission, with color centers or
colloids serving as electron sources, is important
in these cases and not only for alkali halides. There arc 2

after X-ray irr!adiation a considerably increased TL up to

It is pointed
out that ifthe measm.!ement is made at a lower displacement rate of

ABSTRACT: The theor- of potential molecular electron emission
of metals bombarded
by hot electronegative molecules was investigated. The most
frequently quoted
theories of cbeniemifsion (chemically excited exoelectron
emission), and absorption
and oxidation theories were compared by the authors vith the
hitherto less-known
Izmailov-Furmnm theory of potential secondary emission. The
values of yields cal-
culated according to the original or adapted lzmailov-Purman
theory are compared
vith -the values of yields measured by Geiger on a series of
systems of alkaline
metal-halogen molecultis (also partly oxygen molecules), and
by Lobff and Wdstenhagen
on syt;tems of certain non-precious metals (Al, Fe) with
oxygen or nitrogen molecules

and 37-39 days, there is no difference in the measure of
compensatory adreno-
cortical hypertrophy between male and female animals,
whereas in rats aged
52-56 days, the measure of compensatory hypertrophy is
much greater in the
female. in vitro corticosterone production by the
hypertrophic adrenals in_
creases with age; at the age of 52-56 days, females
produce more cortico-
sterone than males. Following contralateral adrenalectomy
on the 100thl post-
natal day, the compensatory adrenal hypertrophy
significantly decreased in
107 day old female rats, in response to prepubertal
castration. This was
unchanged in male rats as compared with sham-operated
controls. .'Estrone
treatment given prior to puberty increases the measure of
compensatory
hypertrophy in the adult male rat, while it leaves the
hypertrophy un-
changed in the adult female. Prepubertal administration of

before sexual maturation, the corticosterone secretion by
the compensatory
hypertrophied left adrenal increases in adult males and
females alike, whereas
it decreases in adult animals ovariectcmized between the
22-25 day of their
lives. The results indicate that the marked compensatory
hypertrophy observed
in the adult female rat develops in the period of sexual
maturation, in
response to estrcgens. 20 Western, 6 Eastern European
