Abstract:
:The possible origins of the different fluorescence decay components in green plants are discussed in terms of a random walk and Butler's bipartite model. The interaction of the excitations with the photosystem II reaction centers and, specifically, the regeneration of theses excitations by charge recombination within the reaction centers, are considered. Based on comparisons between fluorescence decay profiles, time-dependent exciton annihilation and photoelectric phenomena, it appears that the fast 200 ps decay component corresponds to primary energy transport from the antenna to the reaction centers and is dominant in filling the photosystem II reaction centers.
