Abstract | Electrochemical and optical behavior of sputter deposited CeO2, Ce-Zr mixed oxide and Ce-V mixed oxide thin films are reported. The films were deposited starting from a target prepared by mixing and weakly pressing the oxide powders in the desired molar ratio. Li intercalation was accomplished from a liquid electrolyte. CeO2 and Ce-Zr mixed oxide thin films are transparent in the visible range and behave as passive material upon oxidation/ reduction. During the cyclic voltammetries performed on the thin films a charge of few mC was reversibly cycled. The diffusion coefficient was evaluated from galvanostatic intermittent titration technique (GITT) experiments. Ce-V mixed oxide thin films showed a mixed anodic/cathodic behavior passing through a transparent state. The charge reversibly inserted during cyclic voltammetry at 10 mV/s was as high as 22 mC/cm2 for a 107 nm thick film and ranks Ce-V mixed oxide among the most promising materials for electrochromic devices. |
