英文摘要	Shape evolution of one-dimensional (1D) single-crystalline ZnO nanostructures, which were produced via a facile microemulsion-based approach, was clarified by SEM observations by stepwise prolonging the reaction time. It suggested that at the initial stage the nucleation process dominated and the shape of ZnO nanostructures was preferably confined by the microemulsion droplets and took spherical forms. With the extension of the reaction time, the growth gradually governed the process and the shape of ZnO nanostructures evolved to 1D by experiencing a nanoparticles and nanorods coexistance period. The evidenced evolution process from nanoparticles to high aspect ratio and single crystalline 1D nanostructures suggested that the formation process might involve a directed aggregation growth process mediated by microemulsion droplets, in which microemulsion droplets play an important role in modulating crystal size and shape through controlling nucleation rate and nuclei size at the initial stage. On the basis of this postulation, we can control the diameter and aspect ratio of 1D ZnO nanostructures by altering the chain of the cosurfactant or the molar ratio of quaternary microemulsion components. The proposed formation mechanism of 1D ZnO nanostructures is useful for understanding shape evolution and provides guidance for the morphology control of other nanostructures in a microemulsion-based system.; Chemistry, Multidisciplinary; Crystallography; Materials Science, Multidisciplinary; SCI(E); 65; ARTICLE; 2; 309-313; 4
