End-to-End Assembly of Shape-Controlled Nanocrystals via a Nanowelding Approach Mediated by Gold Domains

Welding nanocrystals for assembly: The welding of Au domains grown on the tips of shape‐controlled cadmium chalcogenide colloidal nanocrystals is used as a strategy for their assembly. Iodine‐induced coagulation of selectively grown Au domains leads to assemblies such as flowerlike structures based...

Description
Summary:Welding nanocrystals for assembly: The welding of Au domains grown on the tips of shape‐controlled cadmium chalcogenide colloidal nanocrystals is used as a strategy for their assembly. Iodine‐induced coagulation of selectively grown Au domains leads to assemblies such as flowerlike structures based on bullet‐shaped nanocrystals, linear and cross‐linked chains of nanorods, and globular networks with tetrapods as building blocks.
