Abstract

In thepresent work, the emission and excitation spectrain Li2SO4-Cu crystalshave been obtainedby the methods of vacuum-ultraviolet and thermoactivation spectroscopy. We have studied the nature of emission from a pressed and annealed sample of Li2SO4-Cu powders. It has been revealed that at low temperatures Cu0-SO. -centers are formed during the trap of electrons by Cu+ -centers and during 4 localization of SO. 4 -radicals in the form of localized hole centers.
