摘要：

Catalyst supported growth of In2O3 nanowires and nanoneedles was carried out by chemical vapor deposition on the silicon substrate. Field emission scanning electron microscope result presents that the growth temperature has a significant effect on the shape and morphology of In2O3 nanostructures. Structural analysis revealed that the In2O3 nanowires and nanoneedles are single-crystalline nature with a cubic crystal structure. Room temperature photoluminescence of In2O3 nanostructures shows broad and intense UV emission centering at 375 nm. Hydrogen gas sensor based on the In2O3 nanowires exhibits more faster and better response than In2O3 nanoneedles. (c) 2010 Elsevier B.V. All rights reserved.
