Vanadium Characterization in BTO:V Sillenite Crystals

niques, to characterize the (VO 4)3 absorption bands in BTO:V samples. In this work, the growth process of an optical quality vanadium doped BTO crystal (BTO:V) and a more detailed study of the vanadium oxidation state, is reported. For optical characterization of the crystals, visible and infrared absorption were used.

Vanadium Wikipedia

Vanadium is a chemical element with symbol V and atomic number 23. It is a hard, silverygrey, ductile, malleable transition metal. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) somewhat stabilizes the free metal against further oxidation.
