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 powerful platform for dynamic control of exciton–plasmon coupling.
