DETERMINATION OF THE ABSOLUTE FLUORESCENCE QUANTUM YIELDS OF LASER DYES USING PHOTOACOUSTIC SPECTROSCOPY

A new technique of photoacoustic spectroscopy measurements of the absolute fluorescence quantum yields has been investigated and used in laser dye solutions.The fluorescence quenchers is used in the experiment.Five home-made dyes,Rhodamine 6G,Disodium Fluorescein,Eosin Y,Cuomarin 1 and Quinine Bisulphate,have been measured.The results are in excellent agreement with those reported.
