A new method is developed to obtain crystalline nanorods of WO 3 using tungsten organometallic compound, tungsten hexacarbonyl, at a low temperature of around 700°C. The diameters of the nanorods were in the range of 20–50 nm, and their lengths were up to several micrometers. The WO 3 nanorods had a clean surface without any particles. HRTEM and SAED pattern analysis results showed that the synthesized WO 3 nanorods had a monoclinic single-crystalline structure.
