Intrinsic emission and electron-hole trapping centers in crystals Li2SO4-Cu
In the present work, the emission and excitation spectra in Li2SO4-Cu crystals have been obtained by 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-SO4--centers are formed during the trap of electrons by Cu+-centers and during localization of SO4--radicals in the form of localized hole centers.
