The fluorescence quantum yields and oscillation energies of rhodamines in aqueous micellar solutions (sodium dodecylsulfate was used as the micelle-forming agent) have been studied as a function of the concentration of nitro- and dinitrobenzenes (NB and DNB). The constants of intramicellar quenching and constants of distributions of the quenchers between the aqueous and micellar phases have been determined. A 2--2.5-fold increase in oscillation energy of micellar solutions of rhodamines in the presence of NB and DNB was observed. The effect is explained by the inhibition of the process of formation of the photoproducts causing induced loss during lasing.
