This article is published with open access at Abstract We reported the optical and wettability properties of aligned zinc oxide micro nanotube arrays which were synthesized on zinc foil via a simple hydrothermal method. As-synthesized ZnO micro nanotubes have uniform growth directions along the 0001 orientations with diameters in the range of 100-700 nm. These micro nanotubes showed a strong emission peak at 387 nm and two weak emission peaks at 422 and 485 nm respectively and have the hydrophobic properties with a contact angle of 121 . Single ZnO micro nanotube-based field-effect transistor was also fabricated which shows typical n-type semiconducting behavior. Keywords ZnO Nanotubes Arrays Introduction One-dimensional 1-D nanostructures become the focus of current research because of the unique properties related with their special structures such as high surface-to-vol-ume ratios special compositions etc. 1-15 . They play important roles in fabricating nanoscale functional electronic optoelectronic electrochemical and mechanical devices. Among the numerous 1-D nanostructures 1-D H. Chen X. Wu L. Gong C.
