| Abstract | Porous anodic aluminum oxide (AAO) films were fabricated electrochemically in the mixed electrolyteswith various volume ratios of 0.3M C2H2O4 and 0.3M H2SO4. The transmission spectra with theinterference fringes were measured and the modified Swanepoel method was used to determine theoptical constants of the free standing AAO films. The calculated thickness agrees well with the measuredthickness from the FE-SEM images of the cross section, which indicates that the modified Swanepoelmethod is very fit for the determination of the optical constants of the free standing AAO films.Meantime, with the decrease of the volume ratio of C2H2O4 and H2SO4, the refractive index andthickness of AAO films increase, but the extinction coefficient decreases. The optical band gap isappropriately fitted to the direct transition model proposed by Tauc in the strong-absorption region ofinvestigated films, and is derived from Tauc’s extrapolation. The reasons were investigated. |
