Article Preview

Using a novel approach with low-cost and simple-equipment, the hydrothermal growth of ZnO nanowires array films on glass substrates was carried out after pre-coated ZnO nanoparticle precursor as crystalline nuclei. The physical phase and morphology of the ZnO thin films with nanowires structure were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The results indicate that ZnO films with nanowires array are hexagonal symmetry and highly oriented crystalline array films, which grows along c-axis of ZnO. The diameter of the nanowires is about 60 nm. A strong UV peak, a weak blue band and a weak green band at 399, 469 and 569 nm is observed, respectively, in the photoluminescence (PL) spectra.
