Plasmon-Exciton Resonant Energy Transfer: Across Scales Hybrid Systems

Figure 14

(a) Ultrafast spectroscopic setup with the two distinct lines dedicated to decay time and pump-probe measurements. (b) Delta transmission as a function of average excitation power (from 5 mW to 200 mW, every 10 mW). Double behavior observed in the two spectral regions 510–630 nm (decreasing) and 630–750 nm (increasing). Here vertical axis is the difference between the broadband transmitted intensities of the probe beam in presence and absence of the exciting beam (pump), normalized to probe beam intensity in the absence of pump beam.
