980 nm半导体激光器激发下Er^(3+),Yb^(3+)共掺杂氟氧化物微晶玻璃的上转换发光

Upconversion Luminescence of Fluoro-Oxide Glass-Ceramics Codoped with Er^(3+) and Yb^(3+) under 980 um Pumping

测量了Ｅｒ３＋，Ｙｂ３＋掺杂氟氧化物微晶玻璃的吸收光谱、激发光谱、上转换发光光谱及其强度随泵浦光强的变化，讨论了其上转换发光特性．

The absorb spectra, excitated spectra, upconversion spectra and the relationship between upconversion intensity and pump power of Er3+ and Yb3+ codoped fluoro- oxide glass -ceramics are measured. The concerned upconversion processes are discussed.
