摘　　要：Cuprous oxide(Cu2O) hexapodal branch structure with high uniformity was prepared by a solution phase route using sodium dodecyl sulfate as a capping agent.The shapes of Cu2O crystal(flower-like structure,nanocube and nanoplate) were tuned by varying species and concentrations of surfactants to control the growth rate on different crystal planes of Cu2O.Cu2O nanostructures were characterized by UV-Vis spectroscopy,XRD,TEM and SEM.XRD result shows that the obtained Cu2O belongs to cubic phase.TEM and SEM results demonstrate that specie and concentration of surfactants play a key role in the formation of various morphologies of Cu2O.The formation mechanism is discussed.Moreover,the optical properties of the obtained Cu2O are shape-dependent.Cuprous oxide（Cu2O） hexapodal branch structure with high uniformity was prepared by a solution phase route using sodium dodecyl sulfate as a capping agent.The shapes of Cu2O crystal（flower-like structure,nanocube and nanoplate） were tuned by varying species and concentrations of surfactants to control the growth rate on different crystal planes of Cu2O.Cu2O nanostructures were characterized by UV-Vis spectroscopy,XRD,TEM and SEM.XRD result shows that the obtained Cu2O belongs to cubic phase.TEM and SEM results demonstrate that specie and concentration of surfactants play a key role in the formation of various morphologies of Cu2O.The formation mechanism is discussed.Moreover,the optical properties of the obtained Cu2O are shape-dependent.
