摘　　要：采用电场辅助电化学沉积的方法成功的在阳极氧化铝模板中沉积出ZnO纳米线阵列。透射电子显微镜(TEM)、X射线衍射(XRD)测试结果表明,制备的纳米线是单晶ZnO纳米线,形貌均匀,直径大约为60nm,并且择优于(101)晶面。我们对生长过程中所加辅助电场的作用给出了初步的解释。ZnO nanowires arrays were fabricated in anodized aluminum oxide templates by electric fieldassisted electrochemical deposition method. The result of transmission electron microscopy indicates that the nanowires are straight and uniform. The X-ray diffraction patterns indicate that the nanowires are highly oriented. The result of selected area electron diffraction suggests that the nanowires are single crystals. The photoluminescent spectrum presents a broad-band luminescence in the region of 350- 650nm. The effect of the assisted transverse electric field on the growing process of ZnO nanowires is also discussed.
