Abstract The upconversion luminescence of oxyfluoride transparent vitroceramics codoped with Er³⁺ and Yb³⁺ has been studied experimentally. There are microcrystallites to form in the oxyfluoride glass which is treated over its transition temperature, and the transparent vitroceramics are obtained. The vitroceramics has the better transparency and a high upconversion luminescent efficiency. Our results show that there is strong energy transfer between Er³⁺ and Yb³⁺ in the vitroceramics, which results in the change of the upconversion spectra with intensity of excitation laser.
