摘要: The excited state reactive dynamics of the fluorescence dye molecule, Auramine O, were studied in confined water environment reversed micelles formed by ionic and nonionic surfactants. decays measured up-conversion method with a time resolution <70 fs. time-resolved spectra recreated analysed using one-dimensional generalised Smoluchowski equation assuming time-dependent diffusion coefficient. decay times showed dependence on droplet sizes, reaction was significantly slowed down smallest both AOT surfactant. friction estimated from analysis enhanced media which shows good agreement times. Therefore, we found out that interfacial charges are not required for suppression reaction. Interestingly, slower surfactant than AOT, even when O is similar size droplet.
