摘　　要：针对Na2O-TeO2-WO3体系碲钨酸盐玻璃进行了研究,绘制了该体系完整的成玻区,利用DSC和Raman测试分析了该系玻璃的热稳定性及结构。拉曼测试表明,随着WO3含量的增加,921—951 cm-1处的拉曼谱带强度逐渐变强,且WO3/Na2O值的不同影响该拉曼峰出现的位置;玻璃体系中随着Na2O含量的增加,存在TeO4(tbp)向TeO3(tp)的转变。碲钨酸盐玻璃热稳定性好,成玻区域宽,声子能量比碲酸盐玻璃高,适合作为稀土掺杂宽带光纤放大器的基质材料。Ternary tungsten-tellurite glass system was researched in this paper.The glass system components were Na2O-TeO2-WO3.The complete glass forming region has been obtained by XRD analysis.The thermal stability and structure of tungsten-tellurite glass were determined by means of differential scanning calorimeter(DSC) and Raman spectra.The results indicated that the intensity of the peak observed between 921—951 cm-1 increases as the WO3 concentration increased,and (tbp's) change into (tp's) as the Na2O concentr...
