enhanced phosphorescence analysis

in luminescence spectroscopy
A use of luminescence quenching effects to enhance sensitivity. The strong depopulation of the fluorescing singlet excited state by external heavy atom perturbers can lead to a large population of the phosphorescing triplet excited state.
