| 摘 要： | 详细地研究了Ｐｒ３＋，Ｙｂ３＋ＺＢＬＡＮ玻璃中Ｐｒ３＋和Ｙｂ３＋离子之间的能量传递过程、及能量传递对上转换发光的影响。实验结果表明，在９６０ｎｍ激光泵浦下Ｙｂ３＋通过Ｙｂ３＋—Ｐｒ３＋之间的交叉弛豫向Ｐｒ３＋传递能量。具体的能量传递形式有三种。Ｙｂ３＋作为敏化剂可提高Ｐｒ３＋的上转换发光强度。从Ｐｒ３＋向Ｙｂ３＋的反向能量传递过程也是存在的，具体的过程和Ｐｒ３＋向Ｙｂ３＋传递的相反。Ｐｒ３＋—Ｙｂ３＋的能量传递导致Ｐｒ３＋发光的淬灭，使Ｐｒ３＋上转换发光随着Ｙｂ３＋浓度增加出现饱和。和３Ｐ０能级相比较，Ｙｂ３＋对Ｐｒ３＋离子的１Ｄ２能级发光的淬灭作用更强

| Abstract: | In this paper, the energy transfer processes between Pr 3+ ions and Yb 3+ ions were studied in upconversion luminescence of Pr, Yb:ZBLAN. There are three ways for the energy transfer from Yb 3+ to Pr 3+ . Yb 3+ ions act as sensitisers in the upconversion luminescence of Pr 3+ ions. There are also three energy transfer paths from Pr 3+ ions to Yb 3+ ions, which quenches the luminescence of Pr 3+ ions and results in saturation of luminescence of Pr 3+ ions with the increasing concentration of Yb3+ ions. |
