Abstract
Hexagonal zinc sulfide nanocrystals (ZnS NCs) were prepared under mild solvothermal condition at 170°C with the polymer ester used as ligand for their stability and effective passivation. Well-defined absorption peaks with the largest blueshift of 89nm were observed for the ZnS NCs based on the ultraviolet-visible (UV-vis) absorption spectra analyses compared with that of the bulk one, which are in correspondence with the apparent quantum confinement effects. Well excited states were obtained from UV-vis absorption and photoluminescent excitation (PLE) spectra for the ZnS NCs. PL emission spectra showed dominant band-edge luminescence.
