摘要

本文采用真空紫外光谱和热活化光谱的方法，获得了Li2SO4-Cu晶体的发射光谱和激发光谱。我们研究了Li2SO4-Cu粉末的压缩和退火样品的发射性质。结果表明，在低温条件下，Cu -SO4-中心是在Cu+中心捕获电子和SO4-自由基以局域空穴中心的形式局域化过程中形成的。

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.
