Strong coupling between AuNCs and two different excitonic materials. a AuNC coupled to the J-aggregates. b Experimentally measured scattering spectra and anticrossing behavior curves of AuNC@J-aggregates. c AuNC@J-aggregates coupled to the layer of WS2. d Three-peak spectrum and the temporal dynamics of AuNC@J-agg/WS2 hybrids. Scattering spectra of individual AuNC@J-aggregates/WS2 hybrids with e varying AuNC sizes and f varying the thickness of PMMA between the AuNC@J-agg and the WS2. g Numerical simulated field enhancement of the AuNC@J-aggregates/WS2 system varying the thickness of spacer.
