    ABSTRACT: Well-aligned ZnO nanorod arrays were synthesized on the c-axis orientated ZnO seed layer by chemical bath deposition (CBD) technique. Randomly distributed ZnO microrods with big diameter and growth speed were also formed simultaneously in the same process. The growth of the microrods followed the expected diffusion-limited Ostwald ripening mechanism reasonably well, while that of the nanorods was suggested to be controlled not only by the nutrition ions available but also by the density of nuclei site and the reaction kinetics on the growing surfaces, etc. The microstructure and optical properties of the well-ordered nanorod were also investigated.

    ABSTRACT: Oriented ZnO nanorod arrays and ZnO thin films were simultaneously grown on magnetron sputtered ZnO seed layers through a hydrothermal approach without any metal catalyst. The c-oriented ZnO nanorod arrays were grown on the unannealed ultrathin ZnO seed layer, while the ZnO thin films with (100) preferred orientation were grown on the annealed ultrathin ZnO seed layer. Thermodynamically preferred (002) oriented grain growth will be suppressed by the morphology changes of the ultrathin seed layer while the (100) orientation will preferentially develop instead. Photoluminescence spectroscopy results show that the UV emission peak shifts slightly to shorter wavelength with increasing the annealing temperature of the ultrathin ZnO seed layer.
