Exciton Annihilation in J-Aggregates Probed by Femtosecond Fluorescence Upconversion

Femtosecond fluorescence upconversion was used to study the excited-state dynamics of two-dimensional J-aggregates of a thiacyanine dye. At high intensities the excited-state population decay is faster than exponential and the decay is intensity dependent. A singlet−singlet exciton annihilation deca...
