Indocyanine green in water forms J aggregates, which are observed as a red-shifted narrow absorption band at 890 nm. The fluorescence quantum distribution of the indocyanine green J aggregates was studied by continuous wave laser excitation at 834 nm. A fluorescence quantum yield of phi(F) approximate to 3 x 10(-4) was measured. The fluorescence peak coincides with the absorption peak (no Stokes shift). (C) 1997 Elsevier Science S.A.
