Аннотация:Abstract—We studied the photophysical processes of halogenated fluoresceins (eosin (E), erythrosine (ER),and Rose Bengal (RB)) in aqueous micellar solutions using dynamic light scattering and stationary and timeresolvedfluorescence spectroscopy. The introduction of dye molecules into reverse AOT micelles causes anincrease in their hydrodynamic radii Rh. The kinetics of fluorescence of the studied dye molecules in reversemicelles was investigated. The average time of the excited state decreases with increasing Rh for eosin,erythrosine, and Rose Bengal, which is associated with an increase in the mobility of water molecules and aweakening of the effect of geometric limitation of dye molecules. The degrees of fluorescence anisotropy r ofdye molecules in reverse micelles were measured; the r values in micellar systems are greater than in aqueoussolutions and decrease with increasing Rh. For the studied dye molecules in micellar systems, the rotationalcorrelation time θ was determined, which decreases for all studied dyes with increasing Rh, which indicates adecrease in the microviscosity of a limited aqueous medium inside the micelle. It is found that θE > θER >θRB; that is, the effect of the internal heavy atom appears in the value of the rotational correlation time.
