Paper Abstract

ZnO nano-nails which consist of the nanowire at the top of nanorods have been synthesized by the nanoparticle-assisted deposition technique. When the nanowire was excited by the third harmonics of a Q-switched Nd:YAG laser, the ultraviolet stimulated emission was clearly observed from single nanowire, indicating the high crystalinity of the nanowire. The highly sensitive ultraviolet photo-detectors were successfully fabricated by trapping these nanowires between electrodes using the dielectrophoresis technique.
