摘要

Colloidal synthesis of kinked ultrathin ZnS nanorodsanowires with mixed phases using tiny Ag2S nano crystals as catalysts is reported It is found that chloride ions can induce the controlled morphology transition from straight to kinking. The synthetic parameters modulating the growth of kinked ZnS nanorodsanowires are systematically investigated Chloride ions introduced in the reaction can generate more proportion of wurtzite phase by slowing the nucleation and growth rates during the growth of one-dimensional (1D) ZnS nanorodsanowires. The formation of kinked morphology is responsible for the increased domains of mixed stacking and twinning in single 1D nanostructures. The present recipe on controlled synthesis of 1D kinked nanorodsanowires provides a model of crystal growth control,and these unique 1D nanostructures may also offer new opportunities to fabricate nano devices with special functions.
