Nano structured copper-zinc oxide thin film synthesis by anodic oxidation method in alkaline media

Anodization process is one of the most flexible methods for synthesis of nanostructured thin films. This study is about anodizing of brass to form a nanostructured film of copper and zinc oxide on surface. These oxides are routinely used in the manufacture of electronic devices due to their favourable band gap energies. In this study, the effect of electrolyte media on the morphology of prepared thin films by anodization method has been studied. The alkaline media containing KOH and NaOH was used for the anodization process. Applied voltage and anodizing time were also the parameters to be studied. The obtained oxide film was characterized by field emission scanning electron microscopy (FESEM) and energy dispersive spectroscopy (EDS). The results confirmed the existence of nano structured copper-zinc oxide on the surface of the brass. Different nano sized morphologies like spheroid, flowerlike, flakes was obtained in different conditions of anodic oxidation.
