vanadium pentoxide (V2O5) have been investigated. UV–Visible spectroscopy
measurements were carried out in order to investigate the optical properties of as grown
V2O5 samples. UV–Visible absorption spectrum shows a shifting in absorption peak
towards lower wavelength from pure to different concentrated as grown samples. Value of
optical band–gap (Eg), estimated from optical measurements, increases from 2.89 to 3.38 …
