Abstract : V2O5 is a versatile material that have controllable transmission, absorption and reflectance that are suitable for electrochromic applications. In this report, the Vanadium pentoxide is modified by doping with titanium using its propoxide precursors. Thin films were fabricated over Florine doped Tin Oxide (FTO) coated glass plate by spin coating technique. Electrochromic properties of V2O5 film is improved by doping with Titanium. X-Ray Diffractometer (XRD), Scanning Electron Microscopy (SEM) analysis and UV Visible absorption and transmission of the prepared films were taken. To study the electromagnetic properties of the thin films, they were annealed at different temperatures for 30 min. Temperature dependence on optical properties of Ti-V2O5 films were analysed by absorbance and transmittance spectrum. We optimised the fabricated films for its electrochromic properties at temperatures of 350 °C, 450 °C and 550 °C. Among this the thin film annealed at 450 °C shows better oxidation and reduction peaks. Thus the electrochemical behaviour of thin films (V2O5 doped with Titanium) were studied by the cyclic voltammeter.
