Ultrafast Exciton Response of High Optical Density J-aggregates from Ultrathin Films of Cyanine Dyes

Not Accessible

Your library or personal account may give you access

Abstract

Ultrathin films of cyanine dye J-aggregates show extraordinary exciton cross sections. Exciton dynamics are studied by ultrafast pump-probe and transient photoluminescence spectroscopy. An exciton delocalization length of N=18 monomers was measured at room temperature.
