Paper Abstract

In this paper we report the preparation of glass ceramic based on PbF2GeO2WO3SiO2BaF2 system co-doped Yb3+/Ho3+ rare-earth ions. We prepare the upconversion luminescence glass ceramic sample by investigating prepartion process parameter of this system and selecting doping concentration. In our experiment optimum proportion of Yb3+/Ho3+ rare-earth ion concentration is 6:1. We observe the excitation spectrum by using Japanese Hatachi F4500 fluorescent photometer whose exciting light is 980nm semiconductor laser. There is a strong emission peak at 545nm. By analyzing rare-earth ion energy level and spectral character, we build up the upconversion luminescence mechanical model of this system. This sample has many advantages such as simple preparation process, big dimension, good chemical stability, high mechanical robustness and broad excitation band. It is worth of further research.
