摘要
用高温熔融法制备了摩尔组分百分比为 70TeO2-20(ZnO、WO3、AlO1.5)-9NaO0.5-1ErO1.5的碲酸盐玻璃样品。测量了玻璃样品的吸收光谱和荧光光谱, 用差热分析方法(DTA)测试了玻璃的热稳定性。结合 Judd-Ofelt理论和 McCumber理论分别计算得到了三种玻璃样品的强度参数. t (t=2, 4, 6)、Er3+离子的吸收截面和受激发射截面。据此分析了玻璃样品的内部结构, 比较了三种玻璃样品中 Er3+离子的放大带宽品质因子 (σ epeak × FWHM )和增益品质因子 σ(mpeakeτ×)。结果发现, 分别用 WO3、Al2O3组分替换传统碲酸盐玻璃中的 ZnO组分, 可以将放大带宽品质因子提高 1.3倍和 1.6倍, 放大增益品质因子提高 1.2倍和 1.4倍。另外, Al2O3组分的引入也显著提高了玻璃样品的热稳定性。研究表明, 通过有选择性地改变碲酸盐玻璃组分配比, 可以进一步提高掺 Er3+碲酸盐玻璃光谱性质和热稳定性。
Abstract
Er3+-doped tellurite glasses with composition in mol percent of 70TeO2-20(ZnO, WO3, AlO1.5)-9NaO0.5-1ErO1.5 were prepared by conventional melt-quenching method. The absorption spectra and the fluorescence spectra of the glasses were measured, and the thermal stability of the glasses was measured by the Differential Thermal Analysis (DTA) technique. The glass internal structure was analyzed, and the bandwidth quality factor ( σepeak × FWHM ) and gain quality factor σ were compared among the three glasses based on the intensity parameters. t (t=2, 4, 6) calculated by (mpeakeτ×) Judd-Ofelt theory, and the Er3+ absorption cross-section and stimulated emission cross-section calculated by McCumber theory, respectively. The results show that the bandwidth quality factor can be enhanced by 1.3 and 1.6 times, and the gain quality factor can be enhanced by 1.2 and 1.4 times when the composition ZnO in the tellurite glass was replaced by WO3 and Al2O3, respectively. Furthermore, the thermal stability was increased evidently in the glass containing Al2O3. The studies indicate that the spectral properties and thermal stability of Er3+-doped tellurite glass can be improved through the change of glass constituent.
