Essay

The influence of technological growth parameters on growth coloration of YAlO3 crystals, influence of after-growth thermal treatments and ionizing irradiation on optical properties of YAlO3 and LiNbO3 crystals were established as well as role of rare-earth and transition metals dopants in the coloration processes. The mechanisms of optical absorption changes of YAlO3:Mn crystals under radiation which are associated with recharging of manganese ions were proposed.
