Opis:: The present work is devoted to investigation of optical absorption changes in Fe and Cu doped LiNbO₃ (LNO) single crystals induced during annealing in vacuum and air as well as under influence of the ²⁰⁹Bi ions irradiation with energy 11.4 MeV/u (MeV per nucleon) and a fluence 5×10¹¹ cm¯² at room temperature. The analysis of changes of absorption of the crystal during air annealing have been studied in the Arrhenius coordinates and activation energies have been determined.

Opis:: The present work is devoted to investigation of optical absorption in pure $Ca_4GdO(BO_3)_3$ single crystals in the spectral range 0.2-1.1 μm induced under influence of the gamma quanta irradiation with absorbed dose $2 \times 10^3$ Gy. The effect of heating in air on the absorption spectrum of irradiated sample is also studied.

Opis:: First experimental investigations on absorption and photoluminescence of the novel $Hg_{3}TeCl_{4}$ monocrystals grown by the Bridgman method are reported. A comparison of the measurement results with theoretical band structure calculations of the $Hg_{3}TeCl_{4}$ crystal confirmed that $Hg_{3}TeCl_{4}$ is a wide-band-gap photoconductor ($E_{g}$ = 3.64 eV at 24 K) with the effective masses of charge carriers characteristic for semiconductors. Energetic position of the main photoluminescence peak and its temperature dependence indicates the presence of an additional energy level in the energy gap which takes part in the radiative recombination process and whose origin was discussed.
