Highly ordered ZnO nanowire arrays were fabricated by oxidizing the metal Z
n that was electrodeposited in the pores of anodic alumina membranes (AAMs)
. The diameters of ZnO nanowires range from 15 to 90 nm. Atomic force micro
scope, x-ray diffraction, and transmission electron microscopy observations
indicate the polycrystalline ZnO nanowires were uniformly assembled into t
he hexagonally-arranged nanochannels of the AAM. A green emission band caus
ed by the singly ionized oxygen vacancy in the ZnO nanowires was also repor
ted.
