| We described results of the effect of annealing and irradiation treatments on the optical properties of Y3Al5O12, YAlO3, SrLaGa3O7, LiNbO3, Gd3Ga5O12, LaGaO3, ZnSe, and LiF single crystals. Changes in absorption and luminescence are presented. Recharging processes of uncontrolled impurities (e.g. Fe3+, Fe2+, and Mn2+), and active ions (e.g. Nd3+, Dy3+, Cr4+, Cr3+, and Ce3+), as well as types of color centers produced in the crystals after a particular irradiation or annealing treatment are presented. |
