Abstract
The effect of UV light and light pulses of the integral light of lamps on γ-irradiated LiF crystals with impurities of hydroxyl ions and magnesium were investigated. The optical absorption and luminescence of color centers at different stages bleaching depending on the exposure time of the crystal under UV light or from the number of light pulses were studied. IR spectra of molecular complexes with hydrogen bond and hydroxyl ions at different stages of bleaching are present. The transformation of complexes with a strong hydrogen bond in complexes with a weak hydrogen bond, and vice versa under the action of light are shown. It is presented as molecular complexes with hydrogen bond affect transformations color centers in the process of crystal bleaching.
