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
