摘要：

The intralayer and interlayer aggregation of octadecylrhodamine 6G mixed in a stearic acid matrix have been studied by flash photolysis and picosecond fluorescence methods in Langmuir-Blodgett films. Both intralayer and interlayer dimers relax via their triplet state. The dominant fluorescence quenching process is either excimer formation or cluster fluorescence. The activation energy of excimer formation is 3.8 kJ mol-1.
