Crystallization Behavior and Up-Conversion Luminescence of Er3+-Doped Chalcogenide Glasses
Rare earth doped chalcogenide glass-ceramics possess advantages for luminescence regulation because of their low phonon energy and sulfide nanocrystals. Here, 80GeS2·20Ga2S3 chalcogenide glasses and glass-ceramics doped with different mole fractions Er3+ ions were prepared and investigated via advanced structure and performance characterization. Effect of rare earth content and crystallization on the up-conversion luminescence of Er3+ ions was discussed accordingly. The results show that the introduction of Er causes the decreasing glass transition temperature and onset temperature of crystallization peak, leading to the presence of stronger diffraction peaks corresponding to Ga2S3 phase in the samples containing more Er3+ ions. The crystallization of Ga2S3 nanocrystals enhances the up-conversion by nearly 5 times, and the optimal luminescence doping mole fraction increases from 0.75% to 1%.
