Vanadium dioxide (B-VO2) nanowires were successfully prepared under soft conditions by hydrothermal treatment. Structural analysis and phase identification have been carried out by means of X-ray diffractraction (XRD). The morphological properties of the samples have been examined by scanning electron microscopy (SEM). The XRD results revealed single phase oxide B-VO2 with considerable differences concerning to morphology and cristallinity as observed by SEM and XRD. Moreover, VO2(B) prepared for 96 h exhibited different morphology concerning to grain size and shape as well as dissimilar preference in crystal orientation, as a result of the processing conditions. The possible growth mechanism steps leading to nano-VO2(B) wires-like morphology was also proposed. The optical properties of the samples were evaluated by UV–visible spectroscopy and photoluminescence.
