Abstract
AbstractLarge‐scale In2O3 nanorods, nanocubes and nanowires have been successfully synthesized by chemical vapor deposition route under atmospheric pressure. The structures and morphologies were characterized by x‐ray diffraction (XRD), scanning election microscopy (SEM) and high‐resolution transmission electron microscopy (HRTEM). The growth mechanisms of these In2O3 nanostructures were analyzed in detail based on the experimental results. Field‐emission measurements of these nanostructures demonstrated that nanorods with rectangular cross‐section possessed good performance with a turn‐on field of 2.47 Vμm–1 and a field enhancement factor of 4597. The room‐temperature photoluminescence (PL) spectrum of the In2O3 nanostructure showed UV emission centered at about 396 nm and visible emissions located at 541 and 623 nm.
