Abstract :
V2O5 thin films are prepared by inorganic sol gel technique and spin coated on glass substrates. These prepared films annealed at 473K and 573K temperatures. The as prepared and annealed films were characterized using XRD and transmittance spectra. These films were found to be polycrystalline in nature. Crystallite size decreases with increase annealing temperature and with increase in annealing temperature the optical band gap increased from 2.34eV to 2.5eV.
