Preparation, characterization and application of nanostructured metal oxide thin films

In this paper, thin films of metal oxides (ITO, TiO2 and ZnO) were prepared on a glass substrate by electron evaporization, spin coating and dip coating process. The morphologies, phase structure and the optical properties of the thin films were investigated by scanning electron microscopy (SEM), X-ray diffractometer (XRD), atomic force microscopy (AFM) and optical transmittance measurement which show that the metal oxide/glass films are formed by a layer of nano-sized particles with average diameter of 30-60 nm. The process from gel to crystalline film and the microstructure of the films were investigated by DTA-TG, XRD and SEM. The influence of preparation processes and annealing on the performance of the films was also studied. Optical and photocatalytic properties of nanostructure thin films were investigated for different application.
