ZnS nanowires with wurtzite polytype modulated structure

A novel polytype modulated ID 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).
