Fabrication of Various ZnO Nanostructures and their Photoelectric Properties

Various morphologies of ZnO nanostructures, including nanoparticle (NP), nanopetal and nanorod (NR) array, were fabricated via solution-phase approaches. The morphology and crystallization of resulting Nano-ZnO were investigated by Field-emission scanning electron microscope (FESEM), High resolution-transmission electronic microscope (HR-TEM), and X-ray diffraction (XRD), respectively. A dual-layered photoreceptor containing the nanostructures film as the charge generation layer (CGL) were designed and fabricated. It was found that the photoreceptor based on ZnO NR array as CGL exhibited better photoelectric performance than that from ZnO NP or nanopetal.
