| 摘 要： | 本文报道在约７９８ｎｍ的半导体激光泵浦下，Ｔｍ＾３＋，Ｙｂ＾３＋共渗五磷酸盐非晶的蓝光发射。激光被样品吸收而直接激发Ｔｍ＾２＋离子至＾３Ｆ４能级。从Ｔｍ＾３＋向Ｙｂ＾３＋的能量传递，接着从Ｙｂ＾３＋向Ｔｍ＾３＋的能量传递把Ｔｍ＾３＋离子激发至＾１Ｇ４能级。分析表明，声子在上转换过程中起了很大作用。

| Abstract: | We report the blue upconversion luminescence of Tm3+ and Yb3+ codoped non-crystal pentaphosphate pumped by -798nm laser diode. The samples were directly excited to 3F4 level of Tm3+ ion. Two energy transfer processes between Tm3+ and Yb3+ contribute mainly to the population of 1G4 level of Tm3+. Phonon plays an important role in the upconversion process. |
