高度有序氧化钨纳米棒的制备和表征

摘要:

采用直流磁控溅射法结合阳极氧化法在铝基纳米点阵上制备氧化钨(WO3)纳米棒. 运用原子力学显微镜(AFM), 电子扫描显微镜(SEM), X射线衍射仪(XRD), 电化学工作站(EW)和紫外-可见分光光度计(UV)观察表征了WO3纳米棒的表面形貌、结构、光学性能和电致变色性能. 结果表明: 在溅射过程中, 溅射粒子优先沉积于铝基纳米点阵的凸点上, 然后成核并形成棒状; WO3纳米棒的直径约为200 nm, 与铝基纳米点阵的直径一致, 拥有一定的电致变色性能.

Abstract:

Tungsten oxide (WO3) nanorod arrayswere prepared on an aluminumlatticemembrane by combining direct current (DC)magnetron sputtering and aluminumanodization. The surface morphology was investigated by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The structure and electrochemical properties of the WO3 nanorod arrays were characterized by X-ray diffraction (XRD) and an electrochemical workstation (EW). The optical performance was tested using a UV-Vis absorbance spectrophotometer (UV). Results showed that the sputtered atoms adsorbed preferentially onto the protuberant nanodots of the aluminum lattice membrane during magnetron sputtering and then nucleated and grew into nanorods. The average diameter of the WO3 nanorods is about 200 nm which is in line with the diameter of the alaminum lattice membrence. The WO3 nanorod arrays possess certain electrochromic performance.
