ABSTRACT- The spectra of Sm3+ in Zrd:3S
. ,m-phosphor without melt and with 4% MgC12
melt were analyzed to study the inter-Wation between activator ions and the
,lattice and obtain information Pout radiation composition. The Sm. concentration
was varied between lo-7 gnd 10- gm/gm, and in addition a variable concentration
of silver was added (10- to 10-3 gm/gm). Three types of luminescence centers
were obtained, lying in the red, orange, and yellow-green parts of the spectra.
These were enhanced by changing the phosphor composition. A temperature test
from 20-120C indicated that several radiation bands were formed as a result of
electronic and vibrational frequency combinations. Orig. art. hast 7 figures and

comparison luminors, In order to ascertain the effect exerted on the
composition and on the luminescence yield of variations of the syn-
thesis conditions, luminor composition, and variation of its crystal
lattice. The rare earth elements used as activators were Ce, Pr, Nd.
Sm, Eu, Tb, Dy, Ho, Er, and Tu. The cathode luminescence spectra
were ineasured either photographically or pbotoele2.trically. The
phosphors were excited with an electron beam (10-IJ A/cm-d at 20 kV).
The luminescent spectra of the phospbors,were investigated with an
ISP-51 spectrograph. The measurements were, made at room temperature.
The results are illustrated in Table 1 of the Enclosure, which shows
that the individual rare earth elements have greatly varying activa-
tion efficiency.. A study was also made of the variation of the emis-
sion spectra with change in the CdS composition, using ZnS.CdS-Ho as
an example. The results conclude earlier conclusions that the trans
Ition frequencies in the centerd of rare earth elements are Independ--
ent of the CdS content and of the average lattice.constant, at least
for crystals of the ZnS type. The CdS content affects only the,in-
tegral emission of the phosphor. Original articlelhad'.6 fXgures and

ABSTRACT: The cathodoluminescence spectra were Investigated for ZnS-luminophors
activated with each of the rare earths except Pm, and for ZnS,--CdS mixtures
activated with Ho. The luminophors were prepared at 12000 in an H2S or an NH
atmosphere, and contained 0.01 percent activator by weight. The cathodolumin-
:escence was excited by a 10-6 A/cm:2 beam og'20 keV electrons. The experimental
technique has been described elsewhere CV.L.Levshin, E.Ya.Arapova, A.I.Vlazhevich,_
iet al., Tr.Fiz. In-ta Im. P.N.Lebodeva AN SSSR, 23, 83 (1963)). All but three of
the rare earth activators resulted in cathodoluninescence in the visible region.

Curves are presented for four of the luminophors; for these tho luminescence in-

did not introduce any now ones. The caViodoluminescence intennity was maximum for

ABSTRACT: Although iron-activated zinc sulfide phosphors have been known iince 19-15,
Itho nature of their lLaninesconce mechanism is still obscure. The writers developed a
isynthu!jis procedure for ZnS:Fe phosphors in both powdered and sublimate form. The
initial ZnS, containing less than 10-7 g/g iron, was mixed with the desired aimount of
Fe (nono to 3 x 10-4 g/g) and heated at 12000 c for 90 min in a stream of l[Cl. Both
the powdered and sublimated specimens proved to be sonsitivo to infrared. ZnS without
Fe has one luminescence band peaking at 450 mg; doping with Fe gives rise to another
band peaking at 630 mp; the intensity of this red band increases with the dopant con-
centration, while the blue band gradually weakens. Fig-.tres in the text allow the lumin-I..'-

escence spectra at different Fe concentrations and the dependences of the intensities
of the blue and red bands on the Fe content. Glow curves for the blue and red regions
are also shown. Evaluations are mndo of the trap depth. The glow curve data arc con-.
silsteliL with the results obtained in observing IR-stimulated flashes. A band scheme.".
with two levels near the bottom of the conduction band arvi two levels or groups of
levels near the valence band is proposed. Data on the infrarod response are presentedi
and discussed. It is suggested that the trapping levels responsible for IR-stimulated
light flash may differ from the trapping levels responsible for the thermostimulated
peak at 1550, even though both sets of levels are located at about the same depth,
(O.OG-0.07 oV). Aside from stimulation, infrared also proved to have a quenching
effect, particularly in a certain frequency range. The authors are grateful to Z. Id.

ABSTRACT: The authors investigated the luminescence of unactivated, holmium-activated
and samarium-activated ZnS phosphors containing high and low concentrations of the
blue luminescence centers in order to elucidate the role of the blue centers in the
excitation of rare earth activator centers in ZnS phosphors, and in particular, to
determine whether the extreme view that the rare earth centers can be excited only
through the nediacy of the blue luminescence centers is tenable. Specimens with
different concentrations of the blue centers were obtained by heating the specimens
for different times in a stream of M13. Holmium and samarium were chosen for the
study because it had previously been tound that the hole level in excited sm3+ centers

ABSTRACT: The authors prepared thulium-activated zinc sulfide single crystals and
studied their luminescence. The investigations were undertaken mainly to develop a
technique for preparing rare earth activated zinc sulfide single crystal phosphors.
Hexagonal zinc sulfide single crystals with lengths of up to 10 cm and diameters of
up to 3 cm were grown in a graphite crucible at 18000 in an argon atmosphere at a
pressure of 200 atm, by the technique described elsewhere by L.A.Sysoyev and X.M.
Kraynyukov (Fizika tverdogo tela, 4, 3, 807 (1962)). Crystals grown from a mix con-
taining 0.01;~ of thulium by weight exhibited thulium luminescence only after heating
in a stream of H,2S, which treatment produces zinc vacancies. Heating the crystals in
a stream of NH3, which does not produce zinc vacancies, did not give rise to thulium

TITLE; Adsorption of radioactive isotopes on non-ion-exchange
polymeric adsorbents. 1. Adsorption of' zirconium on
ftoroplast-4 (polytetrafluoroethylene) from
hydrochloric acid solutions
PERIODICAL, Radickhimiya, 1961, Vol.3, No.4, pp. 428-431*
TEXT: So far most studies have been concerned with ion-
exchange and colloidal adsorption of radioactive isotopes. To
establish the features of molecular adsorption of radioactive
-isotopes it is most expedient to study a particular element under
conditions such that it may form uncharged compounds in solution.
In such a base it is possible to consider the molecular adsorption
as a distribution of neutral particles of electrolyte between
!--;quid and solid phases, and to compare the results with distribu-
tion of the element in extraction processes. Zirconium is
parti,.;ularly suitable for such a study as in aqueous solution it
may form neutral complexes of type [Zr(OH)xAx-430 (Ref-5- B.A.Lister,
L.H. McDonald. J.Chem,Soc., 4315 (1952), where A is an anion.

The :cmpositton of the complexes depends on the composition of the
-Dition, In this way we may study adsorption as a function of the
.~clution composition and obtain information ort the dependence of
adsorption on the state of the element in solution in order to
deduce the mechanism of molecular adsorption. The present work
-.ons-iders Zr adnorption on polytetrafluoroethylene (PTFE) from
hydrc~hloric acid solutions, Zr desorption from PTFE surfaces with
-1-ibutyl phosphate (TBP)2 and the extraction of Zr into TBP.
It was ne-essary to take spcaial measures to ensure that tracer
ZZ-95 and --arrier zirconium are in the same state, e.g. as regards
htydrclysis, Adso--ption was studied on polished PTFE discs 5.5 CM2
zn area and 1.5 mm. thick. Surface treatment with hot concentrated
tulphuri~~ acid and water guaranteed rapid and complete desorption
~~f Zr95 while not affecting the adsorption properties. zr95
a-,tiv-ity was measured on torsion counter with Al foil to absorb the
Nb95 P-radiation from the Nb formed in the course of the experiment.

where G is the adsorption in g.atom Zr/cm2 and C is the
.zir:;onium --onLantration in g.atom/mf. For tracer concentrations
K = G/C is independent of C and is a function only of the state
of the Zr~ With increasing Zr concentration the adsorption
approximates to that corresponding to a monolayer, which indicates
'hat adsorption is taking place over the whole surface and not on
J-ndi~7idual parts. The temperature dependence of the adsorption
was studied in 10 N HCI to avoid hydrolytic effects which are also
temperature dependent. The value obtained for the heat of
adsorption on the hydrophobic PTFE surface is 2.2 � 0.2 kcal/mole,
which is usually characteristic for van der Waals adsorption.
The dependen--e of Zr9, adsorption on HC1 concentration may be
explained by the r-hange in state of the Zr with changing H+ and Cl-
~-n~entration. Calculations based on published complex formation
~c-nstants (Ref,12-. A,,S, Solovkin, ZhNKh, Vol.2, 31 611 (1957))
show that the --on,~entration of neutral zirconium species is very
h--gh~ It is fcund that the adsorption increases with the number
--f hydroxyl groups in the neutral zirconium complex; this is
possibly due to the formation of hydrogen bonds between these

.o!jiUM 4n-~o TBP from aqueous solution indicates that in strongly
a--id aolution the Zr is adsorbed -as fZrCl1jjO. The possibility of
remc-~ring zirconium from the PTFE surfi;ce with TBP is good evidence
that the element is adsorbed in a molecular state on the surface of
hydrcphcbi~ polymeric adsorbents.
