Abstract

Measurements of the mean phosphorescence lifetime τP, the delayed fluorescence lifetime τDF, the fluorescence quantum yield φF and the ratios of the phosphorescence quantum yield φP and the delayed fluorescence quantum yield φDF to the fluorescence quantum yield were carried out for acridine orange in poly(vinyl alcohol) films as a function of temperature. On the basis of the results obtained, rate constants were determined for radiative and radiationless transitions from the triplet state, and the quantum yields φT of the triplet state population were found in the temperature range 77 - 300 K.
