摘要 熔制了掺铒碲铌玻璃样品(100-X)TeO2-XNb2O5(X=5,10,15,20mol%),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. Er^3＋-doped （100-x）TeO2-xNb205 （x=5, 10, 15, 20mol%） niobic tellurite glasses were synthesized, and their density, refractive index, glass transition temperature, crystallization temperature, Vickers microhardness, absorption spectra, fluorescence spectra andthe lifetimes of Er^3＋ ：^4I13/2 level were measured. The Judd - Ofelt strength parameters Ωt （t= 2, 4, 6） and the stimulated emission cross-section （σcmi） were calculated by Judd - Ofelt theory and McCumber theory, respectively. The compositional dependence of optical parameters of Er^3＋ in g/ass samples wase investigated. The properties of Er^3＋-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.
