| Abstract: | Results of investigations into the dynamics of light-induced absorption in bismuth titanium oxide crystals doped with calcium (Bi12TiO20:Ca) illuminated with quasimonochromatic light of semiconductor light-emitting diodes at two wavelengths from the set  = 870, 660, and 525 nm are presented. Based on an analysis of the experimental data, a model of charge transfer by defect centers describing the observed phenomena is suggested. |
