摘要：

An analysis of RE2+/3+ energy level positions in ZnS is presented. It is shown that the concepts of Jörgensen's refined spin-pairing energy theory (RESPET) may be extended to charge transfer (sulfur → RE) transitions in ZnS:RE. The theoretical results are verified by photo-electron spin resonance (ESR) studies of 3+ → 2+ photoionization transitions of Eu and Yb in ZnS. It is shown that the 4f-4f luminescence excitation spectrum of Yb3+ has a photoionization nature. The arguments for the binding of a deep exciton by RE3+ complexes are presented and discussed. © 1989.
