FLUORESCENCE DECAY OF 3,3′-DIETHYLTHIACARBOCYANINE IODIDE-SODIUM LAURYL SULFATE SYSTEM: DEAGGREGATION OF THE DYE AND DYE-DETERGENT AGGREGATE FORMATION ABOVE AND BELOW THE CRITICAL MICELLE CONCENTRATION

Abstract
Fluorescence decay of 3,3′-diethylthiacarbocyanine iodide was studied in aqueous solutions of sodium lauryl sulfate. The large change in decay behavior is attributed to the deaggregation of the dye and the formation of the dye-detergent aggregate above and below the critical micelle concentration, respectively.
