Phase formation and structural characteristics of Cd-Pb-S nanopowder compositions produced by modification of CdS powder in a citrate-ammonia solution of a lead salt

Nanopowders obtained by modification of a cadmium sulfide powder in a citrate-ammonia solution of lead acetate have been studied by X-ray diffraction, electron microscopy, and thermal analysis. The type of crystal structure and composition of Cd-Pb-S nanopowders depend on the conditions of their synthesis. The thermoanalytical curves show a well-defined endotherm in the temperature range 284-321 C. The position of this endotherm depends on the duration of contact of a CdS powder with an aqueous solution of a lead salt. Heating nanopowders to 600 C in an argon flow leads to formation of oxygen-containing phases: lead sulfate and cadmium oxide. © 2013 Pleiades Publishing, Ltd

SPECTRAL AND LUMINESCENT PROPERTIES OF NaY1-xTmxGeO4 IN IR RANGE

A new series of olivine-type NaY1-xTmxGeO4 (x = 0.0–0.2), germanates has been prepared. Spectra of luminescence, diffuse reflection, as well as the temperature dependence of the luminescence intensity have been studying.Работа выполнена в рамках ГЗ ИХТТ УрО РАН тема-АААА-А19-119031890025-9

SYNTHESIS OF NEW PHOSPHORS BASED ON Tm3+, Nd3+ OR Ho3+ DOPED GERMANATES BY “WET” CHEMICAL ROUTES

Various “wet” synthetic chemical techniques are widely used for the production of multifunctional inorganic materials. In contrast to the standard high-temperature solid state route, methods based on the dissolution of starting reagents allow one to obtain phases with given particle morphology and particle size distribution. Besides, with this approach, the defect structure can be efficiently controlled by varying the synthesis conditions and solution preparation. These advantages are important for producing luminescent materials.This work was supported by the Russian Science Foundation, project № 16-13-10111
