WebApr 4, 2024 · Phosphorescence. For phosphorescence, things are a bit different (see Fig. 4). There are again an S 0 ground state and the two excited states, S 1 and S 2. Additionally, there is an excited triplet T 1 state which lies energetically between the S 0 and S 1 state. The electrons again have antiparallel spins in the ground state. WebPhotoluminescence is the emission of light from a material following the absorption of light. The word in itself is interesting in that it the combination of the Latin derived word luminescence and the Greek prefix, photo -, for light. Any luminescence that is induced by the absorption of photons is called photoluminescence.
