Vanadium doped gallium lanthanum sulphide glass (V:GLS) displays three absorption bands at 580, 730, and 1155 nm identified by photoluminescence excitation measurements. Broad photoluminescence, with a full width at half maximum of similar to 500 nm, is observed peaking at 1500 nm when exciting at 514, 808, and 1064 nm. The fluorescence lifetime and quantum efficiency at 300 K were measured to be 33.4 mu s and 4%, respectively. From the available spectroscopic data, the authors propose the vanadium ions' valence to be 3+ and be in tetrahedral coordination. The results indicate a potential for the development of a laser or optical amplifier based on V:GLS.
