The conversion of color centers in lithium fluoride crystals at temperatures of 50–490°C

Studies of the photoluminescence spectra of γ-irradiated lithium fluoride crystals during temperature annealing in the temperature range from 50 to 490°C were conducted. Experimental data show that F2 and F3+ color centers decay at different rates as temperature increases. The transformation of the F2 and F3+ centers is accelerated by action of laser radiation on γ-irradiated LiF crystals during annealing.
