Structural and optoelectronic properties of as-synthesized SnO2 nanowires were examined in this study. The SnO2 nanowires were first synthesized by thermal evaporation of ball-milled SnO2 powders in argon atmosphere without the presence of any catalysts, and their structural properties are then investigated by X-ray diffraction, Raman scattering, scanning electron microscopy, and transmission electron microscopy. This investigation revealed that the synthesized SnO2 nanowires are single-crystalline and their growth direction is parallel to the [100] direction. In addition, photoresponse of a single SnO2 nanowire was performed with light with above-gap energy, and different characteristics of photoresponses were obtained for the nanowire at ambient atmosphere and in vacuum. The photoresponse mechanism is briefly discussed in this paper.
