【 摘 要 】

Nanostructured metal oxides have attracted a lot of attention recently owning to their unique structural advantages, and demonstrated promising chemical and physical properties for various applications. In this study, we report the structural and optical properties of vanadium oxide nanoparticles (VO-NPs) prepared via a hydrothermal method. Our results are revealing that the components of VO-NPs films are having a belt-like shape with a uniform size distribution. The nanobelts with very smooth and flat surfaces have a typical length of up to 1μm and a width of about 9-14 nm. Moreover, The UV-Visible spectroscopy revealed an excellent optical propertiesshowing clearly the good stoichiometry and crystallinity of our VO-NPs films. This synthesis method provides a new simple route to fabricate one-dimensional nanostructured metal oxides which is suitable for a large field of applications.
