Effect of Sb-doping on the morphology and the dielectric properties of chrysanthemum-like ZnO nanowire clusters

doi:10.1088/1674-1056/21/9/098001

Abstract Chrysanthemum-like ZnO nanowire clusters with different Sb-doping concentrations were prepared by using the hydrothermal process. The microstructures, morphologies, and dielectric properties of the as-prepared products were characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), field emission environment scanning electron microscope (FEESEM), and microwave vector network analyzer respectively. The results indicate that the as-prepared products are Sb-doped ZnO single crystallines with hexagonal wurtzite structure, the flower bud saturation degree F_d is obviously different from that of the pure ZnO nanowire clusters, the good dielectric loss property is found in Sb-doped ZnO products with low density, and the dielectric loss tangent tanδ _e increases with the increase of the Sb-doping concentration in a certain concentration range.
