Abstract

Vanadiumdopedgalliumlanthanum sulphide glass (V:GLS) displays three absorption bands at 580, 730, and 1155nm identified by photoluminescence excitation measurements. Broad photoluminescence, with a full width at half maximum of ∼500nm , is observed peaking at 1500nm when exciting at 514, 808, and 1064nm . The fluorescence lifetime and quantum efficiency at 300K were measured to be 33.4μs 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.
