摘要

The upconversion luminescence of oxyfluoride transparent vitroceramics codoped with Er3+ and Yb3+ has been rnstudied experimentally. There are microcrystallites to form in the oxyfluoride glass which is treated over its transirntion temperature, and the transparent vitroceramics are obtained. The vitroceramics has the better transparency rnand a high upconversion luminescent efficiency. Our results show that there is strong energy transfer between rnEr3+ and Yb3+ in the vitroceramics, which results in the change of the upconversion spectra with intensity of rnexcitation laser.
