In this paper, the preparation of glass ceramic based on PbF2+GeO2+SiO2+WO3 system co-doped Yb3+/Ho3+ rare-earth ions is reported. The upconversion luminescence glass ceramic sample is prepared by investigating preparation process parameter of this system and selecting doping concentration. The optimum proportion of Yb^/Ho^ rare-earth ion concentration is 6:1. It is found a strong emission peak at 545 nm. By analysing rare-earth ion energy level and spectral character, an upconversion luminous mechanical model of this system is proposed. This sample has many advantages such as simple preparation process, big dimension, good chemical stability, high mechanical robustness and broad excitation band.
