摘要：

The Ce3+ and Dy3+ codoped oxyfluoride glasses and glass ceramics containing LaF3 nanocrystals have been prepared in the reducing atmosphere. The emission intensity and Commission International de I'Eclairage (CIE) chromaticity coordinates of the Ce3+ and Dy3+ codoped glasses significantly changed with concentration ratio of Ce3+ to Dy3+. The emission intensity of both Ce3+ ions and Dy3+ ions in the 3.0% Ce3+ and 3.0% Dy3+ codoped glass ceramics increased significantly in comparison with that in the glass. The glasses and glass ceramics could emit bright white light by adjusting the concentration ratio of Ce3+ to Dy3+.
