Optical properties and electronic structure of V_2O_5, V_2O_3 and VO_2

摘要

The electronic structure of the three main vanadium oxides-V_2O_3, VO_2 and V_2O_5-is reviewed. The optical properties of vanadium pentoxide thin films were determined. It was found that a direct allowed transition is the most probable one in the studied vanadium pentoxide thin films.
