Simplified Jablonski diagrams depicting the processes involved for a fluorophore in the three possible situations discussed in the text: (a) Standard fluorescence; (b) SEF in the slow-dynamics regime, in which the vibrational decay rate is faster than the enhanced emission rate of slow-dynamics SEF; and (c) SEF in the fast-dynamics regime, in which the vibrational decay rate is slower than the enhanced emission rate of fast-dynamics SEF.
