Abstract

The Ce3+ and Dy3+ co-doped oxyfluoride glasses and glass ceramics containing CeOF or CeF3 nanocrystals have been prepared in the reducing atmosphere. The crystallinity increased significantly with the Ce3+ concentration, while the crystal size of nanocrystals is mainly influenced by the annealing temperatures. The glasses and glass ceramics emitted white light, deriving from a combination of the Ce3+ blue and the Dy3+ yellow light. The emission intensity and CIE chromaticity coordinates of the Ce3+ and Dy3+ co-doped glasses can be tuned by adjusting the ratio of Ce3+/Dy3+ concentration or the annealing temperature.
