Determination of the oxidation state and coordination of a vanadium doped chalcogenide glass
Abstract
Vanadium doped chalcogenide glass has potential as an active gain medium, particularly at telecommunicationswavelengths. This dopant has three spin allowed absorption transitions at 1100, 737 and578 nm, and a spin forbidden absorption transition at 1000 nm. X-ray photoelectron spectroscopy indicatedthe presence of vanadium in a range of oxidation states from V+ to V5+. Excitation of each absorptionband resulted in the same characteristic emission spectrum and lifetime, indicating that only oneoxidation state is optically active. Arguments based on Tanabe–Sugano analysis indicated that the configurationof the optically active vanadium ion was octahedral V2+. The calculated crystal field parameters(Dq/B, B and C/B) were 1.85, 485.1 and 4.55, respectively.
