Abstract
Indium oxide (In2O3) 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 In2O3 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 In2O3 film prepared by spin coating method is a promising candidate for photovoltaic device applications. (C) 2012 Elsevier B.V. All rights reserved.
