A General Approach to the Synthesis of Gold–Metal Sulfide Core–Shell and Heterostructures


  • This work was supported by Hong Kong RGC Direct Allocation (Project Code: 2060332) and the Joint Research Scheme between NSFC and Hong Kong RGC (Reference: N_CUHK448/06, Project Code: 2900318).


Cores and effect: Water-dispersible core–shell structures and heterostructures incorporating gold nanocrystals of different shapes (polyhedra, cubes, and rods) and a variety of transition metal sulfide semiconductors (ZnS, CdS, NiS, Ag2S, and CuS) are synthesized using cetyltrimethylammonium bromide-encapsulated gold nanocrystals and metal thiobenzoates as starting materials.
