    • Abstract


      Kinetic analysis of the energy level scheme of a dye molecule yields expression for the fluorescence quantum yield. The quantum yield is dependent on molecular parameters and laser pulse characteristics. Calculations show quenching of fluorescence quantum yield due to excited state absorption. Earlier studies on quenching of fluorescence have been discussed quantitatively under an optically thin approximation.
