摘要：

Co3O4 films were deposited on glass and FTO (F:SnO2) substrates by different solution molarities (0.05-0.20 M) through nebulizer spray technique. The crystalline quality of the films was evaluated by X-ray diffraction. The morphological variation of Co3O4 films for different solution concentration was observed from scanning electron microscopy. Optical constants (n and k) and dispersion energy parameters were calculated by fitting the transmittance curves using Swanepoel envelope method. The electrical parameters such as sheet resistance and activation energy were estimated using four probe method. The electrochromic performance of the films was analyzed by electrochemical measurements such as cyclic voltammetry, chronoamperometry, chronocoulometry and optical contrast studies.
