摘要:
Dispersed fluorescence spectra of single molecules of pentacene in p-terphenyl at 1.8 K have been recorded by tuning the excitation laser to single-molecule features at the long-wavelength edge of the fluorescence excitation spectrum. The main vibrational features in these spectra are similar in frequency and intensity to those obtained from the bulk sample with excitation near the center of the origin band, indicating that the absorption features in the wings of the inhomogeneous distribution probably arise from normal pentacene molecules to within the resolution of this experiment. Prospects for the development of this technique are discussed.
