制备了碲酸盐玻璃样品70TeO2-(15-x)B2O3-xNb2O5-15ZnO-1wt%Er2O3(TBN,x=0,3,6,9,12,15 mol%).测试了玻璃样品的热稳定性和光谱性质.根据Judd-Ofelt理论计算了TBN玻璃中Er3+离子的强度参数(Ω2=(5.42～6.76)×10-20 cm2,Ω4=(1.37～1.73)×10-20cm2,Ω6=(0.70～0.94)×10-20 cm2),发现随着Nb2O5含量的增加,Ωt(t=2,4,6)先增加后减小.研究表明Er-O键共价性主要受基质玻璃中非桥氧数的影响,而阴阳离子间电负性的影响可以忽略.应用McCumber理论计算了Er3+离子的受激发射截面(σe=(0.77～0.91)×10-20 cm2)和Er3+离子4I13/2→4I15/2发射谱的半高宽度(FWHM=65～73 nm).比较了不同基质玻璃中Er3+离子的荧光半高宽和受激发射截面.结果表明TBN玻璃系统具有较好的带宽性能,是一种制备宽带光纤放大器的潜在基质材料.
