摘要：

Up-conversion luminescence properties and energy-transfer processes in Er3+, Yb3+ and Tb3+ single doped or co-doped oxyfluorogermanate glasses were studied under 980nm laser excitation. Green and red up-conversion emissions around 524, 546 and 658nm which can be assigned to the Th3+ : D-5(4)-> F-7(J)(J =5 and 0) and Er3+ : (H-2(11/2), S-4(3/2) and F-4(9/2))-> I-4(15/2) transitions, respectively, were strongly observed at room temperature. Up-conversion luminescence intensity depended on the YbF3, TbF3 concentration and excitation power density. The energy transfer processes among Er3+, Yb3+ and Tb3+, and up-conversion mechanisms were discussed.
