Abstract: Using Zn（S₂CNEt₂）₂ as single-source precursor and Au as a catalyst,hexagonal ZnS nanowires with different diameters were synthesized by chemical vapor deposition（CVD） at different temperatures.When using Ni instead of Au as a catalyst,carbon nanotubes could be obtained.When using S and Zn instead of Zn（S₂CNEt₂）₂ as starting materials,cubic phase ZnS nanowires could be prepared.Both the phase-and size-controlled synthesis of ZnS nanowires and the selective synthesis of ZnS nanowires and carbon nanotubes were achieved in the paper.The synthesized products were characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,energy-dispersive X-ray spectroscopy（EDS） and transmission electron microscopy（TEM）.
