ZnS Nanowires with Wurtzite Polytype Modulated Structure


  • The work was supported by a grant from the Research Grants Council of the Hong Kong SAR, China (Project No. CityU 3/01C (8730016)) and a Strategic Research Grant of the City University of Hong Kong (Project No. 7001175).


A novel polytype modulated 1D structure has been grown in ZnS nanowires via intermittent laser ablation–catalytic growth. The polytype modulated ZnS nanowires show a strong blue-shifted bandgap emission centered at 338.2 nm due to quantum size effects. The Figure shows a dark-field image of one of the nanowires (top) and the corresponding electron diffraction patterns (bottom).
