摘要：
A simple controllable chemical bath deposition method was successfully developed to prepare ZnO rods and disks at low-temperature. The crystalline structure and morphologies of the prepared ZnO were characterized with X-ray diffraction (XRD) and scanning electronic microscopy (SEM), respectively. The XRD results proved that the ZnO belongs to wurtzite structure. SEM images showed that the morphology of ZnO was evolved from rod shape to disk shape just by changing the precursor concentration. The aspect ratio (length/diameter) of ZnO crystal decreases from 9.7 to 0.15. And the formation mechanism of these morphologies was discussed. Besides, the photoluminescence (PL) properties of ZnO architectures were investigated at room temperature, indicating that ZnO obtained were highly crystallized. (C) 2012 Elsevier B.V.
