glass ceramics under infrared (1.06 μm) excitation were investigated at room temperature.The upcoversion of infrared radiation into blue emission(20920 cm
-1
and 22173 cm
-1
) from Tm
3+
ion was observed.The upconversion processes involve three or four-photon absorption for these blue emission bands.In order to select the optimum concentration of TmF
