摘要
An optical organic semiconductor microcavity in the strong coupling regime containing J-aggregates (1,1'-diethyl-2,2'-cyanine (PIC)) as optically active material has been investigated. Stable thin layers of homogeneously distributed aggregates were prepared by spin-coating of a specific salt of this dye [(PIC+)(2)B10H102-] without the need of a polymer matrix. Transmission and photo luminescence measurements reveal an anticrossing that is typical for the strong coupling regime. Compared with inorganic semiconductors, a large Rabi splitting of approximately 25 meV was observed in the transmission and photo luminescence measurements. (C) 2001 Elsevier Science B.V.
