Effect of Polymerization on the Fluorescence Lifetime of Eosin in Water
It is known that the fluorescence lifetime and the quantum yield of some organic compound solutions decrease as the solution concentration increases and this phenomenon has been attributed to the interaction of the excited molecules with the nonexcited molecules of the same kind and the formation of polymers.(l)–(4) We report further study of the effect of polymerization on the fluorescence lifetime of eosin in water using the ultrafast optical gate technique to measure the fluorescence lifetime of this solution in various concentrations and various temperatures.
