Luminescence properties of amalgamation-type J-aggregate of cyanine dyes A model of mixed molecular clusters

We fabricated the mixed J-aggregate consisting of 5,5′-dichloro-3,3′-diethyl-9-phenyl-thiacarbocyanine chloride and 3,3′-dimethyl-9-phenyl-4,5,4′,5′-naphthothiacarbocyanine chloride. Based on intrinsic optical spectra and the coherent potential approximation (CPA) method, the formation of the amalgamation-type J-aggregate is proposed.
