Low Temperature Synthesis and Optical Properties of ZnO Nanowires
ZnO纳米线的低温生长及其发光特性

ZnO nanowire arrays are fabricated on anodized aluminum oxide templates with electric field-assisted electrochemical technology. Transmission electron microscopy results indicate that the nanowires are straight and uniform. 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 photoluminescence spectrum presents a broad-band luminescence in the region of 350-650nm. The effect of the assisted transverse electric field on the growth process of ZnO nanowires is also discussed.
