2. EXPERIMENTAL J-aggregate samples were obtained by squeezing a drop of 1O_2 M aqueous dye solution between two glass slips. The optical density obtained corresponds to six monolayers of dye. Room-temperature fluorescence decay of the J-aggregate was observed by two different techniques, time—correlated single-photon i-Partially supported by NSF grants #PCM—8O—l8488 and #PCM—8O—1l8l9 and the sponsors of the Laser Fusion Feasibility Project of the University of Rochester. *present address: Bell Laboratories, Holmdel, NJ 07733.

N2 - Time-resolved fluorescence decay of the J-aggregate of the title dye has been measured with a jitter-free picosecond streak camera and by time-correlated single photon counting. The observed decay is sensitive to the excitation intensity, and the dependence can be simulated by a model involving singlet-singlet exciton annihilation at high exciton densities. The estimate of exciton mobility from this exciton annihilation experiment is similar to results from fluorescence quenching experiments.
