The Fabrication and Photoluminescence Property of ZnO Nanosheets

摘要

Sheet-shaped zinc oxide nano-particles were prepared by hydrothermal method. The zinc oxide nanosheets were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence spectrum (PL) at room temperature. The strongest diffraction apex of the nanosheet-shaped zinc oxide is assigned to <001> crystal planes and exhibits obvious preferred orientation which is different from that of the general zinc oxide. The results show that ZnO nanosheets with about 1000nm× 600nm× 60nm are obtained. The growth mechanism of the ZnO nanosheets was discussed.
