Optical and thermal reducing of photochromic effect in Al doped Bi₁₂SiO₂₀ crystals
Results of experimental studying the processes of reversible optical and thermal reducing of the photochromic effect in Bi₁₂SiO₂₀:Al crystals are presented. It is shown that the optical reducing is the most effective in the region hν = 0.5 - 2 eV and at hν > 1.4 eV the reducing process passes to...
