Opis:: The work is devoted to investigation of stable coloration induced by gamma radiation from $\text{}^{60}Co$ (1.25 MeV) in pure and neodymium doped $Ca_{0.28}Ba_{0.72}Nb_{2}O_{6}$ single crystals. Nature of the induced absorption is discussed. This absorption is due to charge change of native defects or ions forming of crystals (vacancy, niobium ions, etc.). The nature of color centers responsible for induced absorption is discussed.

Opis:: This work is devoted to experimental study of the effect of manganese concentration on thermoluminescent properties of $YAlO_{3}:Mn$ crystals grown by the Czochralski method. A new type of emitting centers beside of $Mn^{4+}$ and $Mn^{2+}$ ions was revealed at low concentration of manganese ions in the crystal. These centers are responsible for the high-temperature thermoluminescent peak at 570 K. A potential of this thermoluminescent peak for thermoluminescence dosimetry application is discussed.

Opis:: The work presents experimental results of an in situ investigation of the $OH^{-}$ absorption in pure and MgO-doped $LiNbO_{3}$ crystals during reducing (95% Ar + 5% $H_{2}$) and oxidizing $(O_{2})$ high-temperature treatments in the temperature range from room temperature to 820 K. The absorption spectra measured in situ at high temperatures in reducing/oxidizing atmospheres have been analyzed. The origin of the changes in optical absorption caused by heating of the crystal is discussed in terms of the OH-bonds orientation change.
