| 摘 要： | 熔制了掺铒碲铌玻璃样品(100-XTeO2-XNb2O5(X=5,10,15,20 mol%)，测试了其密度、折射率、转变温度、析晶温度、维氏机械强度、吸收光谱、荧光光谱、荧光寿命等参量。利用Judd-Ofelt和McCumber理论分别计算了铒离子强度参量Ωt (t=2, 4, 6)和受激发射截面σemi的大小，研究了掺铒碲铌玻璃样品光谱参量对Nb2O5成分的依赖性，并与典型的碲锌钠玻璃（75TeO2-20ZnO-5Na2O）在热学、机械强度、光谱性质和放大品行四个方面进行了比较. |

| Abstract: | Er3+-doped(100－x) TeO2－xNb2O5(x=5,10,15,20 mol%) niobic tellurite glasses were synthesized,and their density,refractive index,glass transition temperature,crystallization temperature,Vickers microhardness,absorption spectra,fluorescence spectra and the lifetimes of Er3+: 4I13/2 level were measured. The Judd-Ofelt strength parameters Ωt(t=2,4,6) and the stimulated emission cross-section (σemi) were calculated by Judd-Ofelt theory and McCumber theory,respectively. The compositional dependence of optical parameters of Er3+ in glass samples wase investigated. The properties of Er3+-doped niobic tellurite glasses were compared with that of the typical 75TeO2－20ZnO－5Na2O(TZN) tellurite glass in aspect of thermal,mechanical,spectroscopic properties and amplification merit. |
