Picosecond time-resolved near-IR spectra of C60 excited states by pump-probe measurements using a probe beam based on broad-band optical parametric generation

Abstract

Picosecond time-resolved absorption spectra of C₆₀ singlet and triplet excited states are observed in the near-IR region in the region 700–1300 nm by the pump-probe technique using a probe beam based on broad-band optical parametric generation (OPG) in β-barium borate (BBO) pumped by a picosecond laser pulse at 532 nm and using an InGaAs multichannel detector.
