Growth of Ultrathick CuInS<sub>2</sub> Shells for Supersized Core/Shell Nanoparticles
The growth of ultrathick shells on quantum dots (QDs) has been demonstrated to provide new aspects of nanoparticles (NPs). Spherical dot-shaped CuInSe<sub>2</sub> QDs were produced with the advantage of shell growth due to their homogeneous surface. The superthickness (∼45 nm) of CuInS<sub>2</sub> was deposited on the CuInSe<sub>2</sub> dots to form supersized CuInSe<sub>2</sub>/CuInS<sub>2</sub> core/shell nanostructures with a tetrakaidecahedron shape to ∼100 nm. This quasi-epitaxial growth mechanism was extended to form supersized ZnSe/CuInS<sub>2</sub> and CuInS<sub>2</sub>/CuInS<sub>2</sub> core/shell nanostructures, thereby providing an efficient method for supersized nanoparticles based on shell growth. The formation of supersized nanoparticles (20-100 nm) may induce new chemistry and physics for nanomaterials, supplying new aspects in fundamental research and the commercial industry.
