| Abstract
| - A general synthetic method has been developed to precisely control the shape and size of ZnS nanorods,nanowires, whiskers, and hierarchical nanostructures. The control was achieved owing to creation of specificgrowth conditions while adopting carefully selected catalysts and tuning their size during a catalytic vapor−liquid−solid growth process. The UV−vis absorption spectra of small diameter ZnS nanorods show a blueshift compared with large diameter ZnS nanowires, thus displaying a quantum confinement effect highlyvaluable for novel nanoscale optoelectronic devices. It is envisaged that it is possible to controllably growother nanostructures using the analogous approach.
