摘要/Abstract

摘要： 以TeO2、ZnO、La2O3为基质制备了掺铒离子的碲酸盐发光玻璃，应用J-O理论计算得到光谱强度三参量，以及铒离子原子组态各个能级的跃迁辐射寿命、荧光分支比及积分发射截面。发现积分发射截面较大（大于10-18 cm），表明具有较好的激光发射特性。基于稀土离子4f能级的丰富性，分析了Er3+离子能级之间发生能级交叉弛豫的可能性，并指出了其在上转换和量子剪裁中的应用前景，为单掺与多掺稀土离子碲酸盐发光玻璃的进一步应用提供了实验依据和理论参考。

Abstract: Tellurate luminescent glass doped Er3+ is prepared with TeO2, ZnO, La2O3 as matrices. J-O theory is applied to calculate the three spectral intensity parameters, and the transition radiation lifetime, fluorescence branching ratio and integral emission cross section in each energy level of erbium ion atom configuration. It is found that the integral emission cross section is larger (greater than 10-18 cm), which shows good laser emission characteristics. Based on the abundance of 4f energy levels in rare earth ions, the possibility of energy levels cross relaxation between Er3+ ions is analyzed. Its application foreground in up-conversion and quantum cutting is also pointed out. It provides experimental basis and theoretical reference for further application on the single or multiply doped rare earth ions in tellurate glass.
