The comparative analysis of thermoluminescent properties of Ce-doped single crystalline films (SCF) of Lu2SiO5 (LSO) and Y2SiO5 (YSO) orthosilicates, grown by LPE method from two different (PbO and Bi2O3) fluxes were performed in this work. We show that the difference in technology of material preparation resulted in different thermoluminescent behaviors of LSO:Ce and YSO:Ce SCFs caused by the formation of the Pb2+-Ce4+ and Bi3+-Ce3+ centers in them.

The magnetic properties and magnetocaloric effect of single crystals RCoGaO4 (R = Lu, Yb) layered cobaltites were investigated. The strong anisotropy of magnetic susceptibility for YbCoGaO4 crystal confirms its Ising spin glass behavior while in LuCoGaO4 crystal Heisenberg-like spin glass phase is observed.

High quality thin epitaxial films of Lu3(Ga,In)5O12:Eu3+ with high effective atomic number were grown by liquid phase epitaxy method. Excitation and emission spectra of Lu3(Ga,In)5O12:Eu3+ epitaxial films were studied under UV and X-ray excitations. The photo- and X-ray luminescence spectra of Eu3+ ions in Lu3(Ga,In)5O12:Eu3+ are characteristic to the f→f transition in the Eu3+ ions that occupied dodecahedral sites in the garnet structure. The ratio of the bands intensities in luminescence spectra under different types of excitation was determined.

Hybrid organic-inorganic composites (HOIC) on the basis of 2-hydroxyethylmethacrylates (HEMA) - tetraethoxysilane (TEOS) were obtained by the methods of sol-gel synthesis and photoinitiated polymerization in a wide range of the composition system changes. The kinetics of photoinitiated polymerization of the obtained composites depending on time of gelation has been studied. The influence of the HOIC composition on their thermomechanical properties and parameters of their molecular structure was investigated.

Samples of undoped yttrium and gadolinium tantalo-niobates with common formulae RE(NbxTa1-x)O4, where RE = Y or Gd, and x = 0-1, have been obtained by solid-state reaction. Optical and luminescent characteristics in visible and UV spectral regions have been studied. The most intense luminescence is determined for yttrium tantalo-niobates with intermediate value of Nb content in the matrix and for heavy Nb - doped gadolinium tantalo-niobates.

The results of the effect of mechanical strain on magnetic anisotropy, the direction of magnetization vector and domain structure of ferrite-garnet film, rigidly connected with the zirconium-titanium lead (PZT) piezoceramic plate are presented. Since such a sandwich structure could be remagnetized both by magnetic field and electric voltage it could be used as the electro-magnetooptical modulator of light or spin switching cell in spintronics.
