英文摘要	用960 nm半导体激光器作泵浦源,研究了Er3+和Yb3+共掺杂的氟氧化物玻璃陶瓷中Er3+的上转换发光的性质.绿光上转换发光是双光子过程,但绿色上转换发光强度与泵浦激光功率是非平方关系,随着泵浦激光功率的增加,上转换发光强度逐渐趋于饱和.用Er3+-Yb3+系统的动力学平衡方程解释了这种现象,在氟氧化物玻璃陶瓷中稀土离子的上转换发光主要是受Er3+和Yb3+之间较强的背向能量传输过程影响的.; The up-conversion properties of Er3+ in the oxyfluoride glass-ceramics codoped with Er3+ and Yb3+ were studied using the 960 nm semiconductor laser as a pumped source.The green up-conversion fluorescence is a double-photon process,but the dependence of the green up-conversion fluorescent intensity on the pumped laser power are not quadratic.The saturation of the fluorescent intensity on the pumped laser power with increasing the pumped power is observed.These experimental phenomena could be well explained by the dynamic rate equations of the Er3+-Yb3+ system.It was concluded that the up-conversion properties in the oxyfluoride glass-ceramic were mainly influenced by the strong back transfer process between Yb3+ ions and Er3+ ions.; This work is supported by the Natural Science Foundation of Tianjin; the National Science Foundation of China for the excellent young researcthers; 国家重点基础研究发展计划(973计划); 0; 12; 1236-1240; 12
