Abstract

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.
