Wet-chemical approaches to multi-component hybrid nanocrystals (HNCs), that incorporate nanoscale domains of different semiconductor, metallic and/or oxide materials interconnected through inorganic junctions, are illustrated and discussed. It is shown how control of interfacial lattice strain and surface energy in liquid media can be achieved within the frame of seeded-growth synthesis techniques, leading to structurally complex HNCs with purposely engineered compositional and geometric parameters. Various topological configurations are analyzed, including concentric core/shell architectures and hetero-oligomers grouping spherical and anisotropically shaped material sections. The most significant chemical-physical properties and technological advantages offered by such multifunctional HNCs are also briefly highlighted.

Abstract
Wet-chemical approaches to multi-component hybrid nanocrystals (HNCs), that incorporate nanoscale domains of different semiconductor, metallic and/or oxide materials interconnected through inorganic junctions, are illustrated and discussed. It is shown how control of interfacial lattice strain and surface energy in liquid media can be achieved within the frame of seeded-growth synthesis techniques, leading to structurally complex HNCs with purposely engineered compositional and geometric parameters. Various topological configurations are analyzed, including concentric core/shell architectures and hetero-oligomers grouping spherical and anisotropically shaped material sections. The most significant chemical-physical properties and technological advantages offered by such multifunctional HNCs are also briefly highlighted.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
