Figure 3: Non-classical light emission from LH2 complexes enhanced by a gold antenna.
From: Strong antenna-enhanced fluorescence of a single light-harvesting complex shows photon antibunching
(a) Photon correlation statistics of single LH2 emission enhanced by a single L=160 nm antenna. The absence of the peak at zero time delay proves non-classical light emission. (b) Sum of 36 cases of single LH2–single antenna emission. The guide lines indicate the average background and peak intensity (red) and the 50% level (green). The time binning was 32 ps. Excitation at λ=800 nm with a repetition rate of 76 MHz. (c) The width of a single coincidence peak shows that the fluorescence lifetime of the LH2 complexes close to the antennas (sum) is strongly reduced compared with an ensemble of LH2 complexes in solution (corrected for the background and normalized to the maximum).
