Paper Abstract

Aerosol-OT (AOT) reversed micelles have been used to simultaneously enhance the fluorescence as well as the thermal lens effect in the analysis of solubilized lanthanide ions. The fluorescence is enhanced because the reversed micelles isolate and protect the analyte from quencher molecules while the thermal lens enhancement is due to the modification of the thermal physical properties of the solvent, i.e., increased dn/dT and decreased thermal conductivity values. Compared to that in water, AOT/CC14 reversed micelles increased fluorescence and thermal lens enhancement factors of TO+ by factors of 2 and 38, respectively. The mechanism for the fluorescence and thermal lens enhancement is discussed.
