Assembly and characterization of a strongly coupled MNP–QD hybrid structure. (A–C) Representative steps in a hybrid structure assembly. A single Au NP (A, Left) was placed in the close vicinity of a single CdSe/ZnS QD (A, Right). (D) Representative PL lifetime measurement of a single isolated QD (black) yielding ∼29 ns and lifetime of the assembled hybrid structure (red) with a fast component of ∼1.6 ns. Solid lines are fits to the data. We used a single exponential function to fit the bare QD lifetime and a double exponential function to fit the hybrid structure, yielding a fast decay of ∼1.6 ns and a slow decay of ∼13 ns.
