Due to the outstanding electrochromic, optochromic, and gaschromic properties, tungsten oxides have attracted great attention and have been investigated extensively. Since one-dimensional tungsten oxide nano materials exhibit superior properties in some promising applications compared with bulk materials, much effort has been made to synthesize tungsten oxide nanowires by using dfferent methods, including a soft-chemistry approach, the chemical vapour deposition (CVD) method, hot-filament-assisted synthesis, flame synthesis and multistage field enhancement of tungsten oxide nanowires.

Tungsten oxide nanowires were prepared by a vapor transport method using yellow tungsten oxide powder as a raw material. The crystal structure and morphology of WO3 nanowires were investigated by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The obtained nanowires were hexagonal WO3.
