Up-conversion luminescence of oxyfluoride glass and glass ceramics containing LaF 3 crystallites doped with Yb 3+ and Er 3+ was investigated at low temperature. Excitation of Yb 3+ in the IR region revealed the fast and the slow components of Er 3+ up-conversion luminescence originating from both gl
## Abstract The frequency upconversion emissions of NaYF~4~ nanocrystals embedded in transparent glass ceramics codoped with Yb^3+^/Er^3+^, prepared by melt quenching and subsequent heating, were investigated. It was found that, compared with that of the sample singly doped with 0.5Er^3+^, the inte
