摘要：

Photo-induced point defects have been compared in pure, heavily aluminum-doped, and iron-containing Bi12GeO20 single crystals. The experimental methods were thermoluminescence (TL), optical absorption, and electron spin resonance (ESR). New TL peaks were observed in the aluminum-doped crystals at 45, 65, 115, and 215 K, and the aluminum dopant was found to suppress some of the TL peaks present in the pure material. The effect of aluminum on the photorefractive process in BGO is discussed.
