摘　　要：在草酸和硫酸电解液中分别制备了孔径为40 nm和20 nm左右的多孔氧化铝模板,用直流电化学沉积的方法,在模板孔洞内电解沉积Zn,对其进行高温下的氧化,可得到高度有序的．ZnO纳米线。扫描电子显微镜观察显示,多晶的Zn纳米线均匀地填充到多孔氧化铝六角排布的孔洞里,直径与模板孔径相当．X射线衍射谱测量证实,制备的Zn纳米线和ZnO纳米线均为多晶结构,并且对比了模板孔径对纳米线结构的影响．测量了多孔氧化铝厚膜和Zn／Al2O3组装体的吸收光谱,发现其在红外波段的吸收系数有逐渐降低的趋势．Semiconductor ZnO nanowires embedded in anodic alumina membranes were fabricated by generating alumina templates with nanochannels, electrodepositing Zn in them, and then oxidizing the Zn nanowire arrays. Their microstructures were characterized by scanning electron microscopy and X-ray diffraction spectrum. The results indicate that the polycrystalline ZnO nanowires were uniformly assembled into the hexagonally ordered nanoehannels of anodic alumina membranes.
