Abstract
A technique for the spectral-kinetic analysis of the photoinduced recombination of radiation-induced color centers in glasses is developed. This technique is used to investigate the sodium silicate glass. The photoinduced absorption spectra of color centers are decomposed into individual Gaussian profiles, and the kinetic dependences of the intensities of these profiles are determined. The absorption spectrum associated with the radiation-induced color centers stable to optical radiation in the spectral range used in this study is separated from the total absorption spectrum of color centers. It is demonstrated that the absorption bands with maxima in the vicinity of 2.0, 2.8, and 4.0 eV are attributed to intrinsic hole centers of different types.
