Abstract
The results of experimental and theoretical studies of the spectral and dielectric properties of garnet Y3Al5O12 crystals are analyzed. The crystals studied were grown under different conditions and were either pure or contained iron-group ion impurities (Ti, Cr, Fe). The crystals were studied before and after irradiation by γ rays and high-energy electrons. A model is proposed for the formation of color centers and their influence on luminescent and other optical and dielectric properties.
