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。 Several ZBLAN glasses doped with different concentrations of Pr3 + / Yb3 + were prepared and their absorption spectra were measured. The luminescent properties of glass with different concentrations were studied by Judd-Ofelt theory and the energy exchange rates of Pr3 + and Yb3 + were studied. The results showed that the introduction of Yb3 + enhanced the pumping of Pr3 + and played a very good sensitization effect.
