Figure 5. Simulations showing excitation and QE enhancements are responsible for the observed bright fluorescence.
(a) Local intensity enhancement |E|2 under plane wave excitation at λ=800 nm around a L=160 nm antenna. Left: in false colour scale. Right: as a function of distance from the surface. (b) Radiative rate enhancement for different distances of a dipole to the end of the antenna, oriented longitudinally with respect to the antenna. (c) Total QE of LH2–antenna system, taking into account an intrinsic 10% QE of LH2. (d) Total fluorescence enhancement for a dipole located at different distances to the NR.
