By means of time-resolved total internal reflection (TIR) fluorescence measurements, rise and decay profiles of the pyrene excimer fluorescence were examined in toluene containing 3.3x 10e4 mol dm-" of poly(methy1 methacrylate) (PMMA, MW= 120000). In addition to a reduction of the fluorescence inten
