Synthesis,Controlling and Photoluminescence Study of ZnO Nanostructures Under Solvothermal-Assisted Heat Treatment
摘要
Abstract
ZnC2O4·2H2O nanorods were prepared in a solvothermal-assisted heat treatment method.Different shapes of ZnO, including nano-cornlike-rod, nanosheet and nanochain, were controlled by different annealing temperatures.The near-band ultraviolet emission spectrum of the corn-like ZnO nanorods had one peak at 400 nm under 250 nm excitation at room temperature.A possible mechanism for the formation of the corn-like solvothermal process would decompose to ZnO at high temperature.In the decomposition process, middle product produced some holes at first, and then produced particles which were stringed to nanorods.As the annealing process continued, nanorods adhibited to nanosheets, and then rolled to nanocorn.Finally, nanocorns dispersed to nanochains.关键词
