Abstract
Assembly of nanostructures is a key step for nanofabrica-tion techniques. Many efforts have been made to assemble nanostructures and to study their properties. Nanoparticles have been assembled into one-, two-, and three-dimensional structures with the assistance of surfactants. Special nano-architectures, such as nanocombs, nanowindmills, and nanote-trapods have recently been reported. Herein we report on new self-assembled nanostructures, i.e., oriented assemblies of ZnS nanowires and nanobelts. The specific structures of the assembled ZnS nanostructures may find applications in nanoelectronics and photonics. It is found that each of the ZnS nanowire bundles acts as a unit, emitting a strong luminescence.
