The aggregation and photo physical properties of fluorescent Cyanine dyes in aqueous and confined reverse-micellar environments were investigated by using steady-state UV-Vis absorption and emission and time-resolved fluorescence spectroscopic techniques. The fluorescent dye molecules were encapsulated in reverse micelles of various sizes. The photo physical properties of the dyes in water as well as in reverse micelles of various sizes were examined by analyzing various photophysical parameters such as quantum yields, band shifts and fluorescence life time etc. Our observation shows that Cy5 dye probably undergoes aggregation inside the smallest reverse micelle of size, which is very significant. Cy5 does behave differently in bigger reverse micelle and in aqueous environment.
