The decrease in delayed fluorescence intensity in anthracene-tetracyanobenzene upon application of an electric field is investigated. It is shown, that photogenerated free carriers are responsible for the observed quenchkg, and rhat the entity quenched is an intermediate state between a triplet-pair
A delayed fluorescence emission of biphotonic nature with the triplet state intermediary is observed from indole ring in low temperature water glasses or in polycrystalline ices. Electron scavengers like CdZ+ions are shown to quench the D.F. emission. A mechanism involving "mobile" electrons or elec
