L 26491-66 ACC NR: AP6013070 is exposed to oxygen, even at low pressure, during heating a cacoAd glow-curve peak appears and this is accompanied by change in the polarity of the photocurrent carriers (from n to p). Various experiments were carried out with pure, self-activatod and impurity-activated ZnS and ZnO (including surface oxidized specimens) and several series of glow curves are reproduced, Data on the polarity of the current carriers in photoconductivity are also adduced. The curves and data demonstrate the effects of the synthesis conditions. A series of phosphogs was prepared by heating different mixtures of ZnS with CuS without flux at 1000 C, followod by reheating with quartz powder (to prevent caking) in sealed tubes at 10500. These ZnS:Cu phosphors were studied immediately after preparation, after various heat treatments and after storage for some months at 200. Their attributes differed considerably, again indicnting the importance of synthesis and other conditions. It Is pointed out that understanding of the peculiarities of the complicated chemical system constituted by copper-activated zinc sulfide luminoph~ors requires further thorough investigation of the ZnS-Cu2S-Cu system.

TITLE: Some Peculiarities in Luminescence Spectra of Sulfide-Selenide Luminophores kNekotoryye osobennosti spektrov 17uminestsentaii sullfid-selenidnykh lyuminoforov) PERIODICAL: Izvestiya Akademii Nauk SSSR, Seriya Fizicheakaya, 1957, Vol 21, #5, pp b67-b6b (USSR) ABSTRACT-. Spectra of luminophores ZnS.ZnSe-Ag and ZnS.Zn8e-Mn were in- vestlgated~ The stability of the So-band was higher than the stability of the Zn-band with respect to the same activator in a sulfide luminophore, and increased with the increase in the concentration of aelonide in the compound. The Un-band, unlike the bands of other activators (Zn,Aggcu, Se), did not shift towards longer wavelengths, when the content of ZnSa in a luminophore was increased. It was discovered that ZnS.ZnSe can be activated also by the metalloid-phosphorus. The independent existence of the P-band Card 1/2 in ZnS,ZnSo was proved by the behavior of this substance during TITLE: Some Peculiarities in Luminescence Spectra of Sulfide-Aelenide Luminophores (Nekotoryye osobennosti spektrov lyuminestsentsii sullfid-selenidnykh lyuminoforov) a calcination in the air and H 2; the Se-band was quenched by calcination in H2, whereas the P-band was manifested under these conditionsi on the contrary, calcination in the air caused the quenching of the P-band and restoration of the Se- band with the initial intensity. The report was followed by a short discussion. One 1~ussian reference is cited. INSTITUTION: Chemico-Technological Institute im.

TITLE: The use of fluidized bed method for an interaction of sulphide-selenide luminophors with gaseous substances PERIODICALt Moscow. Xhimiko-tekhnol6gicheakiy institut. Trudy, No.31, 1960. Isaledovaniya v oblasti khimii i tekhnologii elektrovakuumnykh materialov. pp. 20-28 TEXT; In the majority of cases luminescence af zinc sulphide and zinc sulphide-selenide luminophors is caused by some form of disturbance in the stoichiometry in the main substance of the luminophor - an excess of one of the components of the main ubstance or incorporation of a foreign element. The character : nd the degree of disturbance of the stoichiometry depend on the composition of the gaseous phase in contact with the substance during its ignition. In order to provide a good zont-act between the solid charge andthe gaseous phase of a given composition, the uthors applied the above method of heat treatment to an investi- :ation of self-activated zinc.suiphide and zincsulphideselenide luminophors. The experimental procedure consisted of igniting Card 1/ 3 25970 The use of fluidized bed method for ... S/539/60/000/031/003/014 E036/E135 10-15 g of an appropriate compound in a silica tube fluiclized by a gas of the required composition. The losses of the material with the fluidizing gas were minimized by the self granulation of the charge. In the absence of melting, the granulation was clone by charging somewhat wet material and fluidizing it before ignition. On drying, the charge forms granules from a few tenths to 1-2 mm in diameter. In the presence of a flux, the granulation takes place during the process of ignition. The composition and intensity of luminescent light of variously treated specimens (ZnO in H2S; ZnS + 2% N&CI in argon; ZnS-Ag 1-10-4 + 2% N&CI in argon; ZnS - ZnSe in argon and hydrogen and the same substances in air) was recorded. The extdnction of luminescence of self- activated luminophors after 'their ignition in a stream of' an inert gas indicated that their luminescence was caused by volatile activators zinc and selenium and that the process of extinction is due to the extraction of the attivator from the luminophor's crystals. An ignition in a stream of hydrogen also leads to extinction, but in this case it is caused by an increase in the concentration of the activators. The reversibility of the process Card 2/ 3 259?0 The use of fluidized bed method for... S/539/60/000/031/003/014 E036/EI35 of extinction, shown by the restoration of the output and spectral composition of the luminescence after ignition of an extinct specimen in air, indicates the ease of the exchange of the overstoichiometric zinc and selenium between solid and gaseous phases, as well as the existence of equilibrium ratios between the concentrations of zinc and selenium atoms in the solid and gaseous phases. A non-uniform velocity of extinction of zinc and selenium bands on ignition in argon and in hydrogen proves that the spectral curves of luminophors ZnS-ZnSe and ZnS.ZnSe-Ag which possess one maximum and no inflection points on the side branches, in fact represent a super-imposition of two bands - of zinc (respectively silver) and selenium.

The quenching of the luminescence after calcining the compositions in an inert gas current shows that their luminescence is caused by volatile activators, i, e., zinc and selenium. This quenching is due to zxtraction of the activators from the crystals of the luminescent composition. Calcination in a H 2 current also leads to quenching of the luminescence of sellf-activated compositions. In this case, however, the cause is an increase of activator. concentration.

Isolation of the selenium band in the spectra of the sulphide-selenide luminophors PERIODICAL: Optika i spektroskopiya, v.11, no.5, 1961, 656-66o TEXTs The study of luminophors of the ZnS-ZnSe type, at -196, +20 and +120 OC, with the 30-fold variations of the intensity of excitation, by analysing their afterglow (decay) spectra, showed that the spectra of these luminophors contain two bands. One of these is due to zinc and the other to the introduction of the selenide. It was found that at room temperature and with the increased ZnSe content up to 10 wt.%, there was a steady suppression of the zinc band by the selenium band. When the ZnSe content exceeded 10 wt.% there was smooth displacement of the '0 selenium band only, towards the longer wavelengths. The spectra at -196 IC showed that the centres of luminescence of the blue band of Zn are present up to the ZnSe content of 75 wt.%, The selenium band was isolated and clearly visible in high temperature Card 1/2 32052 Isolation of the selenium band ...

TITLE: Thermodynamic bases of the activation mechanism of sulfide- and sulfide-aelenide luminophores PERIODICAL. Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, v. 25, no. 4, 1961, 445-449 TEXT: This paper has been read at the 9th Conference on Luminecoence (Crystal Phosphors), Kiyev, June 20-25, 1960. It offers a comparison between exDerimental drta, with conclusions being dxawn from a sufficien t-. general thermodynamic %,~evpoint. The authors have proved earlier that thA introduction of neutral activator atoms into the crystal is necessary for the formation of luminescence centers. The results obtained on that occasion, however, are not suited for a thermodynamic study of the con- sequences of temperature- and concentration gradients in the system. The greatest importance is attachnd to clarifying the self-activation mechanism of (Zn, Cd) (S, Se) luminophores. The authors have earlier been able to show that it is sufficient for the self-activation of a ZnS crystal in a Card 1/5 221 '5 3 S/048/61/025//004/002/048 Thermodynamic bases Of... B104/B20 1 sealed space to attain a temperature at which diffusion processes take a sufficiently ra id course. The following processes take place in this connection, (1 passage of a part of sulfide into the vaDor phase to attain the saturation pressure of ZnS molecules in the system; (2) dissociation of sulfides in the gaseous phase. 32 is formed, among others; (3) the neutral discociation products are divided between gaseous phase and the crystal. For every annealing temperature there is a certain concentra- tion of neutral zinc and sulfur atoms. Special investigations, in which it has been attempted to find the causes for the absence of sulfur bands in the spectrum of silf-activated zinc sulfide, have confirmed these views. 7~n(s, se) luminophoresoonstitute a better suited object for checking the above conception. The authors examined the spectra of different composi- -tions of these luminophoresat different excitation intensities in the temperature range of from -1960Cto +1200C. Moreover, also the spectra of the afterglow have been examined. Some of the results are graphically illustrated in Fig. 1. In the behavior of the zinc band the authors note a proof of the dissociation mechanism of self-activation. Fig. 2 presents the concentration of selenium in the luminophore as a function of the " selenium pressure in the gaseous phase. A different mechanism of selenium Card 2/5 22153 3/04 61/025/004/002/048 Thermodynamic bases of... B104%201 introduction may be observed from this diagram. Selenium adds to the anion - lattice sites, and forms positive holes and cation sites. ThO correctness of this assumption has been proved by a method, suggested by .Ryvkin, for determining the sign of the carrier in photoexoitation. The authnre conclude from the results that the penetration of selenium into the ZnS lattice at low pressures is a pure dissolution process. A chemical interaction of atomic selenium with S2- ions begins only at high pressures and concentrations. Sulfur is ejected from the lattice, Se atoms are inactivated and pass over to the basic substance. In the final discussion, A. M. Gurvich acknowledges the benefits derived from the authors' examina- tions, but, at the same time, points out some serious drawbacks: (1) the authors consider the system as consisting of sulfides and dissociation products only; (2) the property of luminescence as a consequence of the appearance of neutral atoms does not follow from the thermodynamic considerations.
