摘　　要：制备了掺铒碲锌铋酸盐玻璃样品84.5TeO2-(15-x)ZnO-xBi2O3-0.5mol%Er2O3(TZBx=0,2,4,6,8,10mol%)。测试和分析了玻璃样品的吸收光谱、荧光光谱和4I13/2能级寿命等参数。根据McCumber理论,计算了Er3+受激发射截面(σepeak=(6.31~8.57)×10-21cm2)、并测量了Er3+荧光半高度(FWHM=65~70nm)。结果表明:适量Bi2O3(~6mol%)的引入,能较好地改善玻璃样品FWHM,σpeeak,4I13/2能级寿命和量子效率等光谱参数。A series of 84.5TeO2-（15-x） ZnO-x Bi2O3-0.5mol%Er2O3（TZB x=0,2,4,6,8,10 mol%） tellurite glasses were prepared.The absorption spectra,emission spectra,lifetime of ^4I13/2 level were measured and investigated.The stimulated emission cross-section（σe=6.31～8.57×10^-21cm^2） of Er^3＋ ions was calculated by McCumber theory and the full width at half maximum（FWHM=65～70nm） of Er^3＋∶^4I13/2→^4I13/2 emission was measured.The results indicate that in tellurite zinc glasses,proper amount of Bi2O3（～6mol%） can be used as a modifier to improve FWHM,σe,lifetime of ^4I13/2 level,quantum efficiency of Er^3＋ ions.
