氟氧化物玻璃陶瓷是具有氧化物的机械性能和氟化物的低声子能量的新型上转换发光材料。本文首次研究了Er3＋-Yb3＋共掺杂时Er3＋的荧光衰减特性。研究结果表明，由于室温下声子的参与使不同稀土离子之间更容易实现能级匹配，增强了交叉弛豫过程，并使664nm辐射在室温下有较长的寿命，这一结果有利于用4F9／2能级做中间能级实现上转换发光。

Oxy-fluoride glass ceramics is a new up-converted luminescentmaterial with strong mechanical strength just like oxide and low phonon energy just like fluoride.Characteristic of Er3＋ luminescent decay is studied firstly.It's found that the energy match between rare earth ions is realized easily by the phonon joining at room temperature,which result to cross-relaxation strengthen and the lifetime of 664 nm radiation be longer.Up-converted luminescent intensity will be increased if 4 F9／2 energy level is used to middle energy level.
