摘　　要：制备了几种掺杂不同Ｐｒ３＋／Ｙｂ３＋浓度的ＺＢＬＡＮ玻璃，测定了玻璃的吸收光谱。由Ｊｕｄｄ－Ｏｆｅｌｔ理论研究了不同浓度的玻璃的发光性质，并研究了Ｐｒ３＋与Ｙｂ３＋的能量交换速率。结果表明，Ｙｂ３＋的引入增强了Ｐｒ３＋的泵浦，起到了很好的敏化作用。Different concentrations of Pr 3+ /Yb 3+ codoped ZBLAN glasses were made. The absorption spectra were measured. The fluorescent properties were calculated by using the Judd Ofelt theory. The energy transfer rates between Pr 3+ and Yb 3+ were calculated. It is shown that the use of Yb 3+ intensifies the absorption of Pr 3+ .
