Description

By the method of pulsed absorption spectroscopy and cathodoluminescence with time resolution formation and relaxation of short-lived radiation defects in pure and impurity crystals of Bi4Ge3O12 (BGO) are studied. Short-lived radiation-induced optical absorption in case of irradiation by dense beams of electrons of near the threshold energy is detected. Spectral and kinetic characteristics of absorption and luminescence induced by powerful electron beam are determined. The influence of iron impurity on the efficiency of generation and relaxation of short-lived absorption is studied
