Spectral Dependence of Absorption Coefficient in Bi12TiO20:Cd Crystal

Abstract

Spectral dependences of absorption coefficient in the range 450-1100 nm for the bismuth titanium oxide crystal doped with cadmium (Bi12TiO20:Cd) are researched. Experimental dependences have been measured up to an irradiation, after an irradiation by a semiconductor light-emitting diode (wavelength of 625 nm) and during process of a relaxation.
