High Resolution Emission Spectra of One Second Delayed Fluorescence from Chloroplasts
In isolated chloroplasts fluorescence emitted seconds after excitation has been assigned to recombination between positive and negative charges stored on the donor and acceptor sides, respectively, of photosystem (PS) II (1–3). This suggests that backreactions bring a PS II chlorophyll molecule to an excited state, supposedly the emitter of delayed fluorescence (4). However, while the spectral composition of prompt fluorescence has been extensively investigated, there have been only a few studies of the emission spectra of microsecond delayed fluorescence and almost none at longer delay times.
