Er~(3+)-Yb~(3+)co-doped transparent oxyfluoride glass ceramics containing SrF_2 crystals were successfully synthesized using a high temperature melting quenching method. The structure, morphology and luminescent properties of the samples were measured and characterized by DSC, XRD, SEM and fluorescence spectra. The results show that the optimum heat treatment temperature is 620 ℃, and the optimum heat treatment tine is 2 h.The effect of Er~(3+)-Yb~(3+)co-doped glass ceramics with different doping concentrations of Yb~(3+)on the up-conversion luminescence properties was discussed. The optimum doping concentration ratio of Er~(3+)-Yb~(3+)is 1∶7. Bright green light(522, 540 nm) and weak red light(656 nm) were observed in the luminescence spectra. The energy transfer process between Er~(3+)and Yb~(3+) was discussed.
