ZnS one-dimensional (I D) nanostructures doped with Mn or Cd have been rapidly synthesized in large scale via a chemical vapor deposition process. Using Zn and S as precursors and MnCl2 Or Cd as doping source, the doped ZnS ID nanostructures were obtained. X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) were employed to characterize the as-synthesized ZnS nanostructures. The catalytically grown ZnS I D nanostructures, including nanowires and nanoribbons, are tens of micrometers in length. All the products are wurtzite ZnS in. structure and preferentially grow along the [001] direction. The room temperature photoluminescence properties of these doped ZnS nanostructures are presented.
