Abstract
This comment concerns some erroneous claims, which arise from the results and discussion in the recent article by A. Rahdar (Journal of Molecular Liquids 220 (2016) 395–403). The mixture of Rhodamine B with AOT/Water/n-Hexane was studied at two water to surfactant molar ratio (Y=10 and 8). Morevoer, The effect of droplet concentration was studied on fluorescence spectra of Rhodamine B-doped droplets. The size of droplet was changed by increase of water to surfactant molar ratio(Y). The results shows, by increase of droplet concentration, the fluorescence (νf) maxima wavenumbers was changed and the absorbance (νa) maxima wavenumbers was constant. We found, the value of νa−νf and νa+νf of Rhodamine B inside of droplets is quite different from the results that found before by A. Rahdar. By theory and experiments, the corrected value of the ratio of dipole moment of Rhodamine B in droplets was reported. We have proven, the ratio of dipole moment was changed between 1.82988 and 2.05972 by increase of droplet concentration at constant molar ratio Y=10. Moreover, the effect of droplet size is reported on the ratio of excited to ground states of dipole moment at Rhodamine B.
