Luminescence properties of Ce~(3+) -doped oxyfluoride aluminosilicate glass and glass ceramics

摘要

Ce3+ -doped oxyfluoride aluminosilicate glasses and glass ceramics were prepared by a melt-quenching method with subsequent heat treatment, and their spectral and scintillation properties were measured and analyzed. The effects of Na+ ions and glass microcrystallization on the spectral and scintillation properties are discussed. Although Na+ ions were favorable for the formation of glass, their photoluminescence and radioluminescence intensity were relatively low. After microcrystallization, the photoluminescence and radioluminescence intensities of the sodium-free oxyfluoride aluminosilicate glass ceramics increased by 2.3 and 4 times, respectively. Microcrystallization of glass is an effective method to improve the scintillation properties.
