Stationary and photoinduced spectra of optical absorption and photoconductivity of undoped and doped (by Cu-, Ag- and Mo-ions) Bi12SiO20 crystals have been investigated in a spectral range of 0.5-3.5 eV. The action of doping on photochromic effect and induced photoconductivity is determined. The temperature dependence of photoinduced optical absorption and photoconductivity is observed. The absence of the correlation is shown between spectral distributions and temperature dependencies of these effects.

Key words: photochromic effect, optical absorption,photoconductivity, sillenite crystals
