Abstract

The optical dynamics of J-aggregates of 1,1′-diethyl-2,2′-cyanine in solution and adsorbed on 4-nm-diameter colloidal silica particles has been studied by using picosecond polarized pump-probe spectroscopy. The absorption anisotropy and the excitation-intensity dependence of the ground-state recovery kinetics are compared in these two systems. The results are discussed in terms of the dynamics of delocalized and localized excitions.
