摘要：
Photoluminescence characteristics and the energy transfer between Ce3+ and Eu2+ in BaLiF3 host lattice have been investigated. A series of concentrations of Ce3+ ion with a fixed Eu2+ concentration in doubly doped BaLiF3:Ce3+,Eu2+ have been studied. According to the defects forming after Eu2+ and Ce3+ entering the host lattice, cerium ions occupy the positions of nearest neighbors of the europium ions. The energy transfer probability and critical distance are calculated. (C) 1999 Elsevier Science Ltd. All rights reserved.
