摘要：
Results of absorption and radioluminescence measurements of YAlO3, Y3Al5O12, LiYF4, LiTaO3, LiNbO3, YVO4 single crystals and Li2B4O7 Single crystals and glasses doped with rare-earth and transition metal ions and LiF crystals were presented. Analysis of excitation energy transfer of X-rays from lattice sites to active ions was performed. Changes in absorption spectra were also analyzed due to gamma -quanta irradiation. Valency change was stated of Nd3+ ions to Nd2+ state after gamma -quanta irradiation of Nd3+ doped LiYF4 single crystal with a dose of 10(5) Gy.
