The singlet and triplet absorption and emission dynamics of C-70 in toluene is studied with a picosecond Nd:glass laser double-pulse pump and probe transmission and fluorescence measurement technique. The singlet S-1 excited-state absorption (sigma(ex,L) approximate to 6 x 10(-17) cm(2)), the triplet T-1 absorption (sigma(T )approximate to 4.2 x 10(-17) cm(2)), and the triplet T-2 absorption (sigma(ex,T) approximate to 4.3 x 10(-17 )cm(2)) at 527 nm are determined. The singlet to triplet intersystem-crossing is studied by double pump pulse induced fluorescence signal analysis and by double probe pulse transmission measurements. The yield of triplet formation is found to be near to unity. (C) 1998 Elsevier Science S.A. All rights reserved.
