Self-assembled highly faceted wurtzite-type ZnS single-crystalline nanotubes with hexagonal cross-sections

Highly faceted wurtzite-type ZnS nanotubes with hexagonal cross-sections have been self-assembled via a thermochemistry process. The self-assembled growth along the c-axis is associated with the non-central and polar surfaces of the ZnS structure (see Figure and inside cover). Photoluminescence at room temperature shows a weak blue and a strong green emission band.
