Intersystem transfer JABLONSKI DIAGRAM

Figure 22.2 Jablonski diagram showing the excitation of a photosensitizer Sens into the excited singlet state Sens which suffers intersystem crossing (ISC) giving excited triplet state Sens. The latter may transfer its energy to ground-state oxygen...

Figure 8 Simplified Jablonski diagram showing the sensitization pathway from the chromophoric hgand L to the lanthanide ion Ln " via the triplet state T of the sensitizer. The k values are the rate constants for aU photophysical phenomena involved. Absorption by the sensitizer, intersystem crossing kisc of the sensitizer, and energy transfer k from the triplet state of the sensitizer to the lanthanide ion (to one of its excited spectroscopic level) resulting in an...

FIGURE 5. Jablonski diagram for [Ru(tpy)2] (tpy = 2,2 6, 2"-terpyridine GS = ground state MLCT = metal-to-ligand charge-transfer kr = rate constant for radiative decay k r = rate constant for non-radiative decay k sc = rate constant for intersystem crossing). 

Figure 1.10 Modified JablonskI diagram Illustrating the antenna effect. Abs - absorption, FI -fluorescence, Ph -phosphorescence, L - luminescence, ISC-intersystem crossing, ET - energy transfer, BT - back energy transfer, NR - non-radiative deactivation, - first excited singlet state, T - lowest excited triplet state, GS - ground state, f - emissive f excited state...
