- Abstract
- Chalcohalide glass with a composition of 65GeS(2)-25Ga(2)S(3)-10Csl (in mol%) doped with 0.6 wt% Tm3+ ions was prepared by conventional melt-quench method. By heat treating the precursor glass at 20 degrees C above its glass transition temperature T-g for different durations, IR transparent glass ceramics were obtained. X-ray diffraction (XRD) and scanning electron microscope (SEM) showed that Ga2S3 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 mu m corresponding to optical transitions of H-3(4) -> H-3(5) and H-3(5) -> F-3(4) of Tm3+ ions were significantly enhanced by the presence of Ga2S3 nanocrystals and reached a maximum after 8 hours treatment.
