摘要

Chalcohalide glass with a composition of 65GeS_2-25Ga _2S_3-10CsI (in mol%) doped with 0.6 wt% Tm~(3+) ions was prepared by conventional melt-quench method. By heat treating the precursor glass at 20°C above its glass transition temperature Tg for different durations, IR transparent glass ceramics were obtained. X-ray diffraction (XRD) and scanning electron microscope (SEM) showed that Ga _2S_3 crystallites were precipitated after heat treatment and their grain sizes were in nano-scale and increased with the elongation of heat treated time. Mid-IR luminescence properties of the glass and transparent glass ceramic samples were investigated. The emissions at 2.3 and 3.8 μm corresponding to optical transitions of ~3H_4 → ~3H_5 and ~3H_5 → ~3F_4 of Tm~(3+) ions were significantly enhanced by the presence of Ga_2S_3 nanocrystals and reached a maximum after 8 hours treatment.
