Abstract
Large scale Sb-doped ZnO nanorod arrays were grown utilizing electrochemical solution method with suitable combination of Zn(NO3)2, HMT and SbCl3 precursors. The influences of the pH value and the substrate on the morphology and the crystallization of Sb-doped ZnO nanorods were investigated in detail. The formed Sb-doped ZnO nanorods were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Characteristics of luminescence and crystal qualities were represented by the room temperature photoluminescence spectroscopy. It was found that the pH value had a great effect on the luminescent intensity of the ultraviolet peak and the defect-related luminescence peak. The Sb-ZnO nanorods with a hexagonal wurtzite structures fabricated under the pH value of 5 showed an intense ultraviolet emission and a weak visible emission, demonstrating the good crystal quality of the nanorods. For the substrates of flexible conductive woven nickel-copper fibers, ITO conductive glass and commercial AZO conductive glass, well-crystallized Sb-doped ZnO nanorods can be all achieved. But the crystallographic orientation of nanorods strongly relied on the substrate type.
