Structural and optical properties of In2O3 nanostructured thin film

Abstract Indium oxide (In 2 O 3 ) nanostructured thin film was successfully deposited on glass substrate by the spin coating method. The film was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS), field emission transmission electron microscope (FETEM), and UV–vis absorption spectroscopy. SEM and TEM observations confirm the formation of In 2 O 3 nanoparticles with average diameter around 20 nm. X-ray diffraction analysis indicates the spherical indium oxide nanoparticles were in single-crystalline phase with body-centered cubic structure. These results indicate that the In 2 O 3 film prepared by spin coating method is a promising candidate for photovoltaic device applications.
