Description

LHCII — the main light-harvesting complex of plants and green algae — is the most abundant membrane protein on earth. Here, we investigate theoretically the effect of exciton-plasmon coupling on LHCII’s fluorescence quantum yield and compare our modelling results to experimental data where plasmon-enhanced fluorescence has been reported in an LHCII–gold nanorod system. One of the models relies on the modified Gersten-Nitzan approach; the other is based on classical plexcitonics. We show that the latter is more robust and leads to more
realistic enhancement factors.
