Plasmon-Exciton Resonant Energy Transfer: Across Scales Hybrid Systems

Figure 18

(a) Real parts of effective permittivity of Ag/Al₂O₃ HMM determined with effective media theory. The Ag/Al₂O₃ HMM shows hyperbolic dispersion at  nm and fabricated HMM structure is shown in the inset. Time-resolved photoluminescence measurements of Coumarin dye on reference and HMM samples: (b) in elliptical region ( = 420 nm), (c) at critical wavelength ( = 430 nm), and (d) in hyperbolic region ( = 450 nm). (e) Lifetimes (first time) of dye on reference and HMM as a function of emission wavelengths. (f) Calculated decay rate enhancement of HMM.
