Abstract
ZnO nanosheet was successfully synthesized on a large scale with a facile and economic hydrothermal method without the assist of template and substrate. The obtained samples were investigated with multiply technique. The sample is composed of a large number of nanosheets with irregular order and is indexed to hexagonal wurtzite ZnO structure structure. The formation of ZnO nanosheets can be attributed to the absorption of OH- onto the polar plane of ZnO crystal. Photoluminescence spectrum indicates that the as-prepared ZnO nanosheets only emit ultraviolet (UV) light centered at 398 nm and may have potential application in the high-quality optical devices..
