摘要：

Among different type of transition metal oxides, tungsten trioxide (WO3) is a suitable candidate for electronic device fabrication due to its n-type property and wide band gap. Herein, one-dimensional tungsten trioxide (WO3) nanorods were achieved from an aqueous solution of sodium tungstate dihydrate (Na2WO4 center dot 2H(2)O) and sodium chloride (NaCl) in an acidic media by a time-optimized hydrothermal synthesis in autoclave at 180A degrees C or different synthesis durations. For studying morphology and size of obtained powder, X-ray diffraction (XRD), scanning electron microscope (SEM), and high resolution transmission electron microscope (HRTEM) were applied. Finally, WO3 nanorods of about 2-3 mu m in length and 100-200 nm in diameter were obtained during 3 h hydrothermal process.
