B2O3含量对掺铒碲铌酸盐玻璃光谱性质及热稳定性影响
CHINESE JOURNAL OF LUMINESCENCE（2007）
Abstract
制备了一系列碲铌酸盐玻璃85TeO2-(15-x)Nb2O5-xB2O3-1%Er2O3 (TNB x=0, 3, 6, 9, 12, 15).根据Judd-Ofelt(J-O) 和McCumber理论,讨论和分析了B2O3含量对掺铒碲铌酸盐玻璃热稳定性及光谱性质影响.研究发现,玻璃开始析晶温度和玻璃转变温度差值ΔT(Tx-Tg),J-O强度参数,FWHM和峰值受激发射截面的乘积在B2O3引入摩尔分数为9%时达到最大值.同时,Er3+:4I13/2能级寿命也随着B2O3含量的增加而单调增加.结果表明,在掺铒碲铌玻璃中,适量的B2O3能较好地提高玻璃的热稳定性能和Er3+离子的光谱性质.
