In order to develop promising materials for the Er{sup 3+}-doped fiber amplifier, transparent glass ceramics containing hexagonal CeF{sub 3} nanocrystals were prepared by melt-quenching and subsequent heating. The obvious Stark splitting in the absorption and emission spectra, the intensification of the 1.53 {mu}m emission, and the prolongation of the Er{sup 3+}:{sup 4}I{sub 13/2} decay lifetime demonstrated the partition of Er{sup 3+} ions into the CeF{sub 3} nanocrystals. Evidently, the efficient cross-relaxation between Ce{sup 3+} and Er{sup 3+}, i.e., Er{sup 3+}:{sup 4}I{sub 11/2}+Ce{sup 3+}:{sup 2}F{sub 5/2}{yields}Er{sup 3+}:{sup 4}I{sub 13/2}Ce{sup 3+}:{sup 2}F{sub 7/2} led to the quenching of the upconversion and the enhancing of the desired Er{sup 3+} 1.53 {mu}m emission. Based on the emission and absorption spectra, it was further calculated that the glass ceramic possesses broad bandwidth as that of the ZBLAN glass, and large emission cross-section close to the silicate glass, for the 1.53 {mu}m emission.
