Abstract : The formation of the anodic oxide film on Pt has been investigated at wavelengths in the visible using voltage scanning ellipsometry. Changes in light intensity in an ellipsometric experiment were used to determine the changes in optical properties of the surface. From these three parameters, the effective complex refractive index and thickness of the surface film have been calculated, using a three-layer model. The anodic oxide film on Au has also been studied using this technique. (Modified author abstract)
