Tony Jun Huang and co‐workers report on p. 3603 on the formation of exciton–plasmon states and in situ dynamic control of coupling strength in Au nanodisk arrays coated with J‐aggregate molecules. By changing the incident angle of incoming light, rather than changing the geometry of the nanoparticles, plasmon–exciton coupling of variable strengths can be observed. The approach enables a simple yet...
Dynamic tuning of plasmon–exciton resonant coupling in arrays of nanodisk–J‐aggregate complexes is demonstrated. The angle‐resolved spectra of an array of bare gold nanodisks exhibit continuous shifting of localized surface plasmon resonance. This characteristic enables the production of real‐time, controllable spectral overlap between molecular resonance and plasmonic resonance. The resonant interaction...
