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. Tungsten oxide (WO3) nanorods were prepared by DC magnetron sputtering combined with anodic oxidation on aluminum-based nanodots. The surface morphology of WO3 nanorods was characterized by atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray diffraction Electrochemical workstation (EW) and UV-visible spectrophotometer (UV) were used to characterize the surface morphology, structure, optical properties and electrochromic properties of the WO3 nanorods. The results show that the sputtering particles have priority Deposited on the bump of the aluminum-based nano-dot matrix and then nucleated and formed into a rod shape. The diameter of the WO3 nano-rod is about 200 nm, which is consistent with the diameter of the aluminum-based nano-dot matrix and has certain electrochromic properties.
