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

PROSPECTS OF RUBBER CRUMB APPLICATION AS A PART OF DEEP OPEN-CAST MINES ROAD COVERINGS
Description
The problem of worn out tires recycling at the mining enterprises is considered. The most important results of influence research of mechanical activation to properties of a rubber crumb and to modified bitumunous concrete properties are discussed

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
