Sensitization Jablonski diagram

Figure 3 Type I and type II photooxidation processes with a porphyrin sensitizer illustrated with a modified Jablonski diagram. (S0 = ground singlet state, Si = first excited singlet state, S2 = second excited singlet state, T,i— ground triplet state, Ti = first excited triplet state, i.s.c. — intersystem crossing.)...

The general picture of lanthanide-sensitized emission is illustrated in the Jablonski diagram in Figure 8. 

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 1. Simplified Jablonski-type diagram of photoinduced catalytic (I), photoassisted (II), and sensitized photoreaction (III) as well as catalysed photolysis (IV). (MLn i + L) represents coordinatively unsaturated species, free ligands as well as ligands and/or coordination compounds with changed formal oxidation number generated by photo-redox and/or photodissociation reactions.
