The spectrofluorimetric behavior of an analytically important molecule eosin yellow was studied in the presence of various surfactant solutions. The relatively weak fluorescence of eosin yellow was significantly enhanced in micellar media formed by cationic and anionic (DBSS) surfactants. The influence of the surfactant structures, concentrations and working experimental conditions on the fluorescence spectra of eosin yellow was thoroughly evaluated and discussed. The solubilizing action of the surfactant has been supplemented by the theoretically calculated spectral parameters like, empirical fluorescence coefficient, quantum yield, molar extinction coefficient and Stokes' shift.
