Abstract

A pulsed photoacoustic system is used to determine the fluorescence quantum yield of diluted dye solutions in highly scattering media. In order to show its accuracy, the quantum yield of Rhodamine 6G in water and ethanol was calculated. The chemical Fuchsin was utilized as a dye reference because the entire excitation energy is converted into nonradiative relaxation processes. The scattering coefficient of the samples was incremented by using spherical silica particles of different sizes and concentrations. The determined mean values in the studied scattering optical density range (03cm1) were 0.95 for ethanol and 0.96 for water. These measurements are in excellent agreement with the best literature values.
