摘要: 制备了掺有稀土发光材料的高折射率玻璃微球,并用XRD、SEM等进行了表征.实验结果表明,该玻璃微球粒经分布范围窄,光学性能好,其折射率为1.93.用改造的显微拉曼光谱仪测量了微球上转换发光光谱,在其荧光光谱上发现了很强的形貌共振,并用光学微腔理论进行了解释.

关键词: 高折射率, 玻璃微球, 稀土玻璃, 制备

Abstract: Glass microspheres doped with rare earth elements were prepared and characterized by powder X ray diffraction (XRD), scanning electron microcopy (SEM), and Raman spectrum and so on. The refractive index is 1.93. The strong morphology-dependent resonances of up conversion luminescence in the microsphere were observed.

Key words: high-refractive index, glass microsphere, glass doped with rare earth element, preparation
