Abstract

SnO₂ nanowires with strong yellow emission centered at 550 nm were obtained by a high-temperature reaction via controlled oxygen flux. Characterization indicated that the products had a tetragonal SnO₂ structure with an average diameter of 100 nm and length up to 100 μm. They also exhibited high photoresponse under an incandescent light, and may have potential application as photoswitches.
