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.

摘要

本文从随机游走和 Butler 的两部分模型的角度讨论了绿色植物中不同荧光衰减成分的可能起源。考虑了激发与光系统 II 反应中心的相互作用，特别是电荷在反应中心内复合时这些激发的再生。基于荧光衰减谱、时变激子湮灭和光电现象之间的比较，快速的 200 ps 衰减成分似乎对应于天线到反应中心的初级能量传输，并且在填充光系统 II 反应中心方面占主导地位。
