摘要：

The spectroscopic properties and energy transfer mechanisms in Ho3+ doped fluorophosphate glasses sensitized by Er3+ and TM3+ at the 2 mu m region are investigated. The absorption spectra and fluorescence spectra of the Tm-Ho doubly-doped glass system and Er-Tm-Ho triply-doped glass system are measured. According to the absorption spectra, the Judd-Ofelt parameters and spontaneous transition probability are calculated and compared with those of other glass hosts. From the fluorescence spectra, the fluorescence intensity of Er-Tm-Ho glass system at 2.0 mu m is 0.95 and larger than that of the Tm-Ho glass system, which is 0.69. Meanwhile, the 2.0 mu m to 1.8 mu m and 2.0 mu m to 1.53 mu m peak intensity ratios in the Er-Tm-Ho glass system are 8.63 and 22.79, respectively, suggesting sufficient energy transfer between Er3+, Tm3+ and Ho3+ ions. In addition, the pumping schemes and energy transfer mechanisms of Tm-Ho doubly-doped and Er-Tm-Ho triply-doped glasses are discussed. The study indicates that the Er-Tnn-Ho triply-doped glass system is a significant sensitized way pumped at 800 nm in fluorophosphate glasses for 2 mu m applications. (C) 2009 Elsevier Ltd.
