文摘

ZnO nanoporous belts with a smooth surface and high pore density have been successfully synthesized; the simple growth method is applicable to produce high-yield single-crystalline ZnO nanoporous belts with a relatively high purity and at a low cost. The morphology and microstructure and optical properties of ZnO nanoporous belts were analyzed by X-ray diffraction (XRD), Fourier transform infrared system (FTIR), scanning electron microscope (SEM), field-emission transmission electron microscope (FETEM), selective area electron diffraction (SAED), and photoluminescence (PL) spectroscopy. Results reveal that ZnO nanoporous belts possess good crystalline quality. The formation mechanism of the special ZnO microstructure is discussed, emphasizing the effect of polar orientation on the nucleation and growth of ZnO nanoporous belts.
