| Summary: | <p>Nanocrystalline spinel copper ferrite CuFe<sub>2</sub>O<sub>4</sub> thin film has been studied and synthesized via the electrodeposition-anodization process. Electrodeposited CuFe<sub>2</sub> alloys were obtained from aqueous sulphate bath. The formed alloys were electro oxidized (anodized) in aqueous (1 M KOH) solution, at room temperature, to the corresponding hydroxides. The anodized CuFe<sub>2</sub> alloy films were annealed in air at 400 <sup>0</sup>C for 2 h. The parameters controlling of the electrodeposition of CuFe<sub>2</sub> alloys such as the bath temperature, agitation and the current density were studied and optimized. The crystal structure, crystal size and microstructure of the produced ferrites were investigated using X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD shows that CuFe<sub>2</sub>O<sub>4</sub> had a spinel structure and the crystallite size of CuFe<sub>2</sub>O<sub>4</sub> phase was 2 nm. SEM micrograph of the formed ferrite particles shows agglomeration structure morphology with a narrow distribution of the particles.</p> |
