Thermally activated delayed fluorescence (TADF) is a process through which a molecular species in a non-emitting excited state can incorporate surrounding thermal energy to change states and only then undergo light emission. The TADF process involves an excited molecular species in a triplet state, which commonly has a forbidden transition to the ground state termed phosphorescence. By absorbing nearby thermal energy the triplet state can undergo reverse int…

Jul 05, 2010 · Delayed fluorescence (DF), also termed delayed luminescence or delayed light emission, is a long-lived light emission by plants, algae and cyanobacteria after being illuminated with light and placed in darkness (Strehler and Arnold 1951). It can last from milliseconds to several minutes, which is by itself an odd phenomenon in an otherwise … Is Accessible For Free: False

This delays the light emission and provides the name for this phenomenon-delayed fluorescence (DF), or delayed light emission (DLE). The DF intensity is a decreasing polyphasic function of the time after illumination, which reflects the kinetics of electron transport reactions both on the (electron) donor and the (electron) acceptor sides of PS II.

Delayed fluorescence (DF) is a fundamental process occurring in all photosynthetic organisms. It is luminescence-produced post-illumination due to charge recombination in photosystem II (PSII) leading to excitation of P680 and the subsequent emission of a photon.
