Abstract

The results of investigation of photochromic effect in Bi₁₂SiO₂₀ crystals doped with V, Cr, Mn, Fe and Cu ions are presented. The optical absorption and photoinduced spectra were investigated in the 0.3 - 3 micrometer range at T equals 80 - 300 K. The contribution of the inherent defects in the form of Bi³⁺ and Bi⁵⁺ ions in Si-lattice sites to photochromic effect was defined. The mechanisms of the photochromic effect are proposed.
