In this work, the effect of substrate temperature on structural and optical properties of V2O5 thin films has been characterized by X-ray diffraction (XRD); SEM and transmission. The films mince has been prepared by Reactive Chemical Spraying technology in Liquid Phase (RCSLP) on glass substrates preheated at (350, 400, 450 and 500 °C). The X-ray diffraction analysis confirms that all layers are polycrystalline, and the preferred orientation of V2O5 is the (001) plane. The morphology of V2O5 thin films are porous nature and their particle’s shape is three-dimensional. The transmittance and absorbance of thin film were measured from which the optical constants (Energy gap, Refractive index, Absorption coefficient, Extinction coefficient and Optical dielectric constant) were determined.
