Abstract

Photophysics of nano-micelles containing crystal violet dye using water-in-oil microemulsion at molar ratio of water- to-surfactant of 10 (W = 10) and different values of mass fraction of water nano-droplets (MFD) by means of spectroscopy was studied. Spectroscopy results showed that in 0.002 concentrations of crystal violet within the microemulsion system, the absorption spectrum of dye was deviated from the Beer's law. The fluorescence emission intensity of the dye at high concentrations of the molecules dye within the AOT microemulsion decreased. The Stokes shift of dye at 0.002 concentrations within the AOT nano-droplet decreased and at 0.00003125 concentrations, behavior of fluorescence was not regular. The polarity parameter (ET(30)) for dye molecules at high concentrations often  indicated a decrease, while in lower concentrations of dye, it generally remained constant. The ratio of the dipole moment ground state to the excited state of dye at high concentration decreased but for the low concentration, it often increased.
