【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。更多还原

【Abstract】 ZnO nanowires arrays were fabricated in anodized aluminum oxide templates by electric field-assisted 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.更多还原
