摘要

The triplet-triplet absorption cross-section spectra of eosin Y, erythrosin B, rose bengal and C_70 are determined in the wavelength range from 390 to 1600 nm. The T_1 triplet state is populated by S_1->T_1 intersystem crossing after singlet state excitation with intense picosecond pump pulses (wavelength 527 nm, duration 6 ps). The triplet-triplet absorption is probed with picosecond spectral light continua passing the samples after excited singlet state relaxation (time delay 20 ns). Absolute triplet-triplet absorption cross-sections are obtained by numerical simulation of the absorption dynamics.
