Efficiency of phosphorescence of the chromophore whether increases or decreases when an iodide ion is added has to be determined. Concept Introduction: In phosphorescence, an intersystem crossing to a triplet state takes place and hence the radiation that is emitted spontaneously will persist for more time. Quenching is the total number of processes that is able decrease the phosphorescence or fluorescence of a molecule. Reactions, electron transfer and energy transfer are examples of the processes that quench the phosphorescence or fluorescence of a molecule.
