Abstract: The optical activity of dye molecules in different environments is of great interest for
many applications such as laser system or biological imaging. We investigate the
fluorescence and absorption spectrum of nano-confined Xanthene dyes (Rhodamine
B and Fluorescein sodium salt) in a two-phase liquid. Each shows very distinct optical
behavior in the water phase of a reverse microemulsion. Their optical properties such
as absorption and fluorescence for different dye and nanodroplets concentration are
investigated. We show that for the same concentration of dye in the microemulsion the
peak of fluorescence intensity is varied by altering the concentration of nanodroplets.
However, the trend of the change is widely different depending on the hydrophobicity
of dyes. Quantum–mechanical second order perturbation theory is used to calculate
the ratio of dipole moments in the ground and exacted states, which accounts for
Stokes shift of fluorescence peak. Photon correlation spectroscopy is employed to
check the trace of dye in the oil phase of the microemulsion
