Abstract
ZnO nanobelts were synthesized by radio frequency (RF) sputtering on copper, silicon and alumina substrates. The sputtering time was 60 min, in argon atmospheric pressure of 40 mtorr. The ZnO nanobelts were characterized by Field Emission Scanning Electron Microscopy, Energy Dispersive Spectroscopy, and Transmission Electron Microscopy for morphology, composition and crystal structure, respectively. From these results, ZnO nanobelts on copper substrate exhibit single crystalline hexagonal structure with size ranging from 10-150 nm, and the length of several micrometers. The morphology of ZnO nanobelt is also influenced by the types of the substrate. These ZnO nanostructures could be further explored for the use as nano gas sensor.
