The Er{sup 3+} doped transparent oxyfluoride glass ceramics containing Sr{sub 2}GdF{sub 7} nanocrystals were prepared and their spectroscopic properties were discussed. The formation of Sr{sub 2}GdF{sub 7} nanocrystals in the glass ceramics was confirmed by x-ray diffraction. The split peaks of the upconversion and near infrared emission bands of the Er{sup 3+} doped glass ceramics can be observed. The upconversion luminescence intensity of Er{sup 3+} in the glass ceramics increased significantly with the increasing heat treated temperature. The luminescence decay curves and time-resolved spectra indicated that the lifetime of the {sup 4}S{sub 3/2} state of Er{sup 3+} in the glass ceramic was longer than that in the glass.
