"WebMotivation of Using Phosphorescence Lifetime Imaging. Phosphorescence occurs when an excited molecule transits from the first excited singlet state, S1, into the first triplet state, T1, and returns from there to the ground state by emitting a photon [24]. Both the S1-T1 transition and the T1-S0 transition are forbidden processes. " - Phosphorescence lifetime imaging
