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).
