Facile synthesis of luminescent AgInS₂--ZnS solid solution nanorods.

higher photon absorption cross-section, [ 4 ] stronger electric dipoles, [ 5 , 6 ] and effi cient one-dimensional electrical transport, [ 7 ] which are related to their anisotropic shape. Over the past few years, a fi ne control over single-component semiconductor nanorods has been achieved by colloidal chemistry routes. [ 8–18 ] However, the growth of multicomponent nanorods has been relatively less developed. This is mainly due to the distinct material components characterized with different physical properties, surface chemistry and morphologies. [ 19 ] The study of multicomponent nanoparticles, consisting of two or more components within each particle, is important both for creating multifunctional nanomaterials and for controlling electronic coupling between nanoscale units. [ 14 ] Recently, great development has been made in the multicomponent nanorods in heterostructures, [ 20–26 ] leading to revolutionary applications in many fi elds such as catalysis, photovoltaic devices, and sensors. For example, Manna et al. [ 25 ] reported the synthesis of CdSe/CdS/ZnS double shell nanorods with high photoluminescence effi ciency biolabeling probes for cell labeling applications. Very recently, highly emissive CdSe/CdS rod in rod core/shell heterostructure with strong linear polarization has been prepared by Banin and co-workers using a seeded-growth approach for potential
