DELAYED FLUORESCENCE IN PHOTOSYNTHETIC MATERIALS: TRANSIENT RESPONSE TO PULSED LIGHT IN CHLORELLA

Abstract

Abstract— The decay of the delayed fluorescence intensity of Chlorella cells following a brief flash of light is investigated in the region of time from 1 msec to 1 sec with greater accuracy than previous investigations. It is found that the best mathematical description for this decay is the sum of several exponential decays and is thought to be evidence for the existence of several distinct components in the production of delayed fluorescence.
