The new results of the luminescence properties investigations of the alkali metals sulphate polycrystals are presented in this review. The main earlier received results are briefly mentioned. It was shown that structure and chemical transformations of those had been realized after a thermal treatment of the polycrystalline sulphate compounds resulted in simple one–atomic and molecular emission centers formation. The basic spectral-luminescence characteristics were established and the conclusions about the nature and structure of respective luminescence centers were made.
