Photonic interaction between quantum dots and gold nanoparticles in discrete nanostructures through DNA directed self-assembly.
Discrete nanostructures of CdSe@ZnS QDs and Au NPs were prepared and the photonic interactions between the QDs and Au NPs were systematically investigated. We found that the Au/QD ratio, separation distances between Au NPs and QDs, and the size of the Au NPs in a given discrete nanostructure all affect the interaction between Au NPs and QDs.
