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
