Abstract:

Early measurements of the optical absorption spectrum of a single impurity molecule in a solid at low temperatures, while intriguing, nevertheless produced insufficient signal-to-noise ratio for the observation of new physical effects. Recent advances in high-efficiency fluorescence excitation spectroscopy have removed this obstacle. For the case of pentacene molecules inp-terphenyl, both stable as well as spectrally diffusing single molecules can be observed.
