Abstract
Measurements of the mean fluorescence lifetime τF, the lifetimes τDF of the delayed fluorescence, the phosphorescence lifetime τP, the fluorescence quantum yields ØF, and the ratios of the phosphorescence and the delayed fluorescence quantum yields ØP and ØDF respectively, to the fluorescence quantum yield ØF were carried out for three acridine dyes: acridine yellow, acridine orange and proflavine in poly(vinyl alcohol) films as a function of temperature. From these measurements, rate constants were determined for the radiative and radiationless transitions for both the lowest singlet excited state S1 and the triplet state T1. The temperature dependence of the efficiency ØT of the population of the triplet state was also examined.
