Tm3+ doped Ga-As-S chalcogenide glass samples were produced using As2S3 pure glass as starting materials. Their photoluminescence properties were characterized and strong emission bands were observed at 1.2 mu m (H-1(5) -> H-3(6)), 1.4 mu m (H-3(4) -> F-3(4)) and 1.8 mu m (F-3(4) -> H-3(6)) under excitation wavelengths of 698 nm and 800 nm. The thulium and gallium concentrations were optimized to achieve the highest photoluminescence efficiency. From-the optimal composition, a Tm3+ doped Ga-As-S fiber was drawn and its Optical properties were studied. (C) 2015 Elsevier B.V. All rights reserved.
