Oil-soluble In2O3 nanoparticles and In2O3-SnO2 nanocomposites were prepared in oleylamine via decomposition of metal acetylacetonate precursors. Thin films of In2O3 and In2O3-SnO2 were obtained by spin-coating solutions of the oil-soluble In2O3 nanoparticles and In2O3-SnO2 nanocomposites onto substrates and then calcining them. Transmission electron microspectroscopy, scanning electron microspectroscopy, atomic force microspectroscopy, X-ray diffraction, ultraviolet-visible absorption, and photoluminescence spectroscopy were used to investigate the properties of the nanoparticles and thin films. The In2O3 nanoparticles were cubic-phased spheres with a diameter of ~8 nm; their spectra exhibited a broad emission peak centered at 348 nm. The In2O3-SnO2 nanocomposites were co-particles composed of smaller In2O3 particles and larger SnO2 particles; their spectra exhibited a broad emission peak at 355 nm. After the In2O3-SnO2 nanocomposites were calcined at 400℃, the obtained thin films were highly transparent and conductive, with a thickness of 30-40 nm; the surfaces of the thin films were smooth and crack-free.
