Snr. Swatton et al., A TIME-RESOLVED DOUBLE PUMP-PROBE EXPERIMENTAL-TECHNIQUE TO CHARACTERIZE EXCITED-STATE PARAMETERS OF ORGANIC-DYES, Applied physics letters, 71(1), 1997, pp. 10-12
We report a novel time resolved double pump-probe experimental techniq
ue that may be used to characterize the excited-state parameters of or
ganic dyes. We show that by monitoring the time evolution of the trans
mittance of a dye after excitation with two pump pulses, the excited s
inglet and triplet absorption cross sections, the lifetime of the exci
ted singlet state, and the triplet quantum yield may all be measured.
This technique has been demonstrated for silicon 2,3-naphthalocyanine
bis(trihexylsiloxide).
