主 题:spectra of photoluminescence point defects thin film electroluminescence.
摘 要:Point defects in the active layer of a layered optimization thin film electroluminescent device of ZnS: Er 3+ were studied. The results indicate that besides Er 3+ substituting for Zn 2+ as luminescent centers, the dominant point defects are sulfur vacancies, zinc vacancies, shallow donors and deep acceptors. Their influence on electroluminescence is
