Abstract

Presented work reports the results of luminescence investigation of thermal treatment influence on the spectral properties of sulphate crystals. The alkali sulphate polycrystalline samples, obtained after annealing and melting, reveal significant photoluminescence, that is not practically observed at the similar conditions for the respective single crystals. Besides, luminescence character depends on the thermal treatment conditions. Changes in the concentration of various type of defects in crystal matrix must be expected under annealing of sulphate crystals at the certain temperatures. Increasing of concentration of some defects creates possibility to their observation by luminescence method. We have investigated absorption, excitation, photo- and x-ray luminescence spectra of alkali sulphate single crystals and powders.
