Vanadium pentoxide or vanadia (V2O5) is one of the few oxides having versatile redox
dependent properties due to the multiple valence state of vanadium and therefore, finds wide
applications in catalysis, electrochromism and sensing.
Vanadium pentoxide thin films were deposited by spray pyrolysis technique. Precursor
solution was prepared with ammonium meta vanadate which dissolved in distilled water to
prepare different concentrations of precursor (such as 0.02 – 0.2M). These precursor
solutions were used to deposit V2O5 films on different substrates (such as glass, flexible, k-
glass etc) at different temperatures (300-500oC).
The vanadium pentoxides were characterized with X-Ray powder diffraction (XRD), and
UV-VIS Spectroscopy.
