CASCADE PHOTON EMISSION IN LUMINOPHORES AND STEREOATOMIC ANALYSIS
01.00.00 Physical-mathematical sciences
Description
The relation between degree of sphericity of the Voronoi-Dirichlet’s polyhedron G3 and the ability to demonstrate the first stage of the cascade luminescence of Pr3+ for several crystalline fluorides and oxygen-containing compounds was revealed. It was found that LaZr3F15 and BaSiF6, with energy level 1S0 located below the bottom of 5d-band, which demonstrate cascade luminescence have the smallest value of G3 among investigated compounds

CONCENTRATION DEPENDENCE OF INTENSITY PARAMETERS OF NEODYMIUM IONS IN STRONTIUM AND LED TUNGSTATES
01.00.00 Physical-mathematical sciences
Description
In the article, the concentration rows of monocrystal strontium and led tungstates doped with neodymium are treated. Judd-Ofelt intensity parameters are calculated

PECULIARITIES OF GROWING NOMINALLY PURE AND NEODYMIUM DOPED STRONTIUM TUNGSTATE SINGLE CRYSTALS
01.00.00 Physical-mathematical sciences
Description
The Nd3+ doped and nominally pure SrWO4 single crystals have been grown by modified Czochralski method. The nature of thermo physical behavior of the growth system with an additional afterheater for crystals with different light transmission was shown. The distribution of Nd3+ ions along the obtained crystals was investigated, the effective distribution coefficient was equal to 0.71

INTENSITY PARAMETERS OF NEODYMIUM IONS IN STRONTIUM TUNGSTATE CRYSTAL
01.00.00 Physical-mathematical sciences
Description
Intensity parameters of neodymium ions in doped SrWO4 monocrystals, grown by modified Czochralski method, are calculated. Changes in the values of these parameters when replacing the tungsten atoms W6+ atoms of molybdenum Мo6+ in the matrices SrMeO4 with the scheelite structure due to less screening of the nucleus Мo6+ compared with W6+ are shown

STRUCTURE AND SPECTRAL-LUMINESCENT PROPERTIES OF THE SILICATES OF RARE EARTHS WITH APATITE STRUCTURE
01.00.00 Physical-mathematical sciences
Description
CaGd4 x y zYbxEryCez(SiO4)3Osingle crystals were grown by the Czochralski method, the concentration dependence of the luminescence decay kinetics of the levels 4S3 / 2, 4I11 / 2 and 4I13 / 2 ions Er3+and X-ray analysis conducted for these crystals. By the results of stereo atomic analysis, it is shown that there is possible to estimate the lifetimes of levels, i.e. predict the probability of multipole interactions
