Abstract
A study is reported of photo- and thermally induced changes in the optical absorption and photoconductivity spectra of Bi12SiO20 crystals in the 0.5-3 .5 eV spectral interval, and of the temperature dependence of optical absor ption for temperatures from 80 to 600 K. An analysis is made of the electro n redistribution processes between the shallow and the deep donor and accep tor levels by invoking the configurational coordinate model.
