please paraphrase this paragraph Fluorescence is a relatively faster phenomenon as compared with phosphorescence because of spontaneous emission of energy from S1 to S0. If it chooses the nonradiative path from S1 to a triplet state, T1 results in the slower decay of the process to reach the ground state S0. During this time interval, quenchers such as molecular oxygen can be involved in phosphorescence emission of the fluorophore. The process of quenching of the excited fluorophore in the triplet...
