✦ Synopsis

The absorption, excitation, iluorescence, delayed fluorescence and phosphorescence spectra together with incident light intensity dependence and decay characteristics of the delayed emissions of the proflavine cation in rigid alcoholic solutions are sholvn and analyzed. Evidence for a triplet-triplet annihilation delayed fluorescence in dye-rigid glass systems is reported for the first time. The possibility of molecular aggregation in these systems is briefly discussed.

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
