Abstract

We present a simple, single step process to produce hierarchical ZnO architectures which involves introduction of Cd(CH3COO)(2) and electrochemical deposition under hydrothermal conditions. Effect of Cd(CH3COO)(2) concentration on the morphology of ZnO films were examined. A variety of hierarchial structures were obtained including micrometer-long micro-channels, 1D twinned structures, 2D ZnO crosses and star flower-like structures by modifying [Cd(CH3COO)(2)/Zn(II)] ratio. Besides surface morphology, the growth mechanism giving rise to the particular structures, crystal structure, phase purity, and chemical binding characteristics of the deposits were examined.
