| Abstract: | Oxyfluoride glass and glass ceramics co doped with Er 3 /Yb 3 ions of the same composition were prepared. Nanocrystals in the glass ceramics were formed,characterized by x ray diffraction and fluorescence spectra. The measurements by using the differential thermal analysis and the crystal parameter calculation by Judd Ofelt theory indicated that the rare earth ions have entered the nanocrystals. At the same time, the ratio of the nanocrystalline phases in glass and glass ceramics before and after annealing was calculated respectively. |
