摘要
Porous anodic alumina (PAA) membranes were prepared in the mixtures of sulfosalicylic acid (SSA) and sulfuric acid (H2SO4) in different concentration ratios. FT-IR analysis reveals that SSA is incorporated in the membranes and the amount of the embedded SSA is depending on the SSA concentration in solution. Absorption and emission spectra of the prepared films exhibit a tunable feature corresponding to the amount of the embedded SSA. These results indicate that certain organic species in the electrolyte can strongly affect the optical behaviors of the anodic alumina membranes by embedding inside the membranes.
