Abstract

ZnOnanoneedle arrays were obtained from the transformation ofZnC2O4precipitate, which was synthesized via electrodeposited method at room temperature. The diameter of those grownZnOnanoneedles is about 80 nm. The XRD pattern and the HRTEM image indicate that the grownZnOnanoneedles have the preferential growth toward (101) direction. The possible growth mechanism of theZnC2O4nanoneedle arrays is proposed and is different from the traditional V-L-S and V-S models. The study on the PL spectrum of thoseZnOnanoneedles shows the near band-edge emission band (379 nm) and the green emission band (510 nm). Especially, a red shift of the green emission band emerges with the increase of the annealing temperature and time.
