Structural Analysis of the TiO2 Thin Films Prepared by Electrochemical Oxidation Using a Two-Step Potential Applying Mode
Based on the anodic oxidation method, titanium dioxide thin films with different morphology were prepared through altering the potential applying mode, the initial potential, the temperature of the electrolyte and the oxidation time. The crystal structures of them were analyzed by X-ray diffractometer. The results indicated that the potential applying mode, the initial potential, the temperature of the electrolyte as well as the oxidation time all have no effect on the crystal structure of TiO2 thin films. The TiO2 thin films obtained under different conditions all show anatase-type, and have the same preferred orientation, but their particle sizes shows great differences.
