Chemosynthesis and characterization of electrochromic vanadium doped molybdenum oxide thin films

A novel aqueous, relatively low temperature thin film growth technique has been developed to fabricate a new generation of smart and nanostructured metal oxide thin film material. Thin films of molybdenum oxide were produced by the chemical bath deposition method. Various levels of doping were achieved by adding small quantities of water soluble vanadium compound to the prepared solution of molybdenum oxide. The change in structural and optical properties in metallic phases were studied and compared to pure molybdenum oxide thin films. The thin films were characterized for their optostructural, morphological and compositional analysis using UV-Vis-NIR spectroscopy, XRD, SEM and EDS techniques. The electrochemical performance of pure and doped thin films was studied in 0.5M H2SO4 as an electrolyte.
