Determination of the oxidation state and coordination of a vanadium doped chalcogenide glass

Hughes, MA; Curry, RJ; Hewak, DW

Abstract

Vanadium doped chalcogenide glass has potential as an active gain medium, particularly at telecommunications
wavelengths. This dopant has three spin allowed absorption transitions at 1100, 737 and
578 nm, and a spin forbidden absorption transition at 1000 nm. X-ray photoelectron spectroscopy indicated
the presence of vanadium in a range of oxidation states from V+ to V5+. Excitation of each absorption
band resulted in the same characteristic emission spectrum and lifetime, indicating that only one
oxidation state is optically active. Arguments based on Tanabe–Sugano analysis indicated that the configuration
of 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.
