Morphology of the leaf-like indium-doped ZnO nanostructures. (a) XRD pattern of the leaf-like indium-doped ZnO nanostructures. (b), (c), and (d) SEM images of the leaf-like nanostructures at different reaction times of 5, 10, and 30 min, respectively. The inset in (c) is a zoom of an SEM view of the leaf-like nanostructure, and the scale bar is 1 μm.
