Fluorescence quantum yield of rhodamine 6G using pulsed photoacoustic technique

Abstract

Experimental method for measuring photoacoustic(PA) signals generated in by a pulsed laser beam in liquids is described. The pulsed PA technique is found to be a convenient and accurate methods for determination of quantum yield in fluorescent dye solutions. Concentration dependence of quantum yield of rhodamine 6G in water is studied using in concentration in quenching region in agreement with the existing reports base3d on radiometric measurement.
