摘要：

ZnO nanostructures were grown by the hydrothermal method on ZnO seed layers post-heated in the range 350A degrees C-500A degrees C. The effects of the post-heated ZnO seed layers on the structural and optical properties of the ZnO nanostructures were investigated by scanning electron microscopy (SEM), x-ray diffraction (XRD) spectroscopy, and photoluminescence (PL) spectroscopy. The average grain sizes in the ZnO seed layers increased with increasing post-heating temperature, and nano-fibrous structures were observed on the surface of the ZnO seed layers post-heated at 450A degrees C. The ZnO seed layers post-heated in the range 350A degrees C-500A degrees C affected the residual stress, lattice distortion in the ZnO nanostructures and the intensity, positions, and full widths at half maximum of 2 theta and PL peaks in the XRD and PL spectra for the ZnO nanostructures.
