本论文研究了在氟化物玻璃中引入TeO_2，以开发用于Er ~（3+）：2.7μ m激光材料的高效玻璃基质。讨论了铒离子的物理化学性质、发光性质以及铒离子周围的局域结构。尽管TeO_2的引入对样品的热稳定性和折射率影响不大，但在发射光谱中可以清楚地看到，随着TeO_2含量的增加，样品的2.7和1.5μ发射强度提高，直到4mol%。根据XRD数据，可以得出结论，在这些样品中没有晶相。XPS谱分析表明，氧阴离子的引入参与了玻璃网络的形成。因此，2.7μ发射率的增加可以概括为铒离子周围对称性的改变。结果表明，Er ~（3+）离子周围的局域结构，特别是与Er ~（3+）阳离子（Er-F）和Er ~（3+）-O键连接的局域结构是引起2.7μ发射的主要因素。基于以上分析，含4mol%TeO2的ZBLAN玻璃有望成为2.7μ m固体激光材料的一种新的选择。
Fluoride glasses with introduced TeO2were investigated in present study to develop efficient glass host for Er3+: 2.7μmlaser materials. The physicochemical properties, emission properties, as well as local structure surrounding erbium ions were discussed successively. In spite of little effects on thermal stability and refractive index with the introduced TeO2, it is clear in the emission spectra that 2.7 and 1.5μmemission intensities were improved with the increase of TeO2until 4mol%. According to the XRD data, it can be concluded that there is no crystal phase in these samples. Based on the analysis of XPS spectra, it was found that the introduced oxygen anions participate in the network forming of glass. Thus, the increased 2.7μmemission can be summarized as the changed symmetrical characteristic surrounding erbium ions. This result indicates that the main factor for 2.7μmemission is local structure surrounding Er3+ions, especially the bonds connected with erbium cations (Er―F and Er―O). Based on above analysis, ZBLAN glass with TeO2(4mol%) might be a new potential choice for 2.7μmsolid-state laser materials.
