Finding a Single Molecule in a Haystack: Optical Detection and Spectroscopy of Single Absorbers in Solids

Abstract

Single-absorber optical spectroscopy in solids is described for the case of finding a single pentacene molecule in a haystack composed of 10 to the 13th power background p-terphenyl host molecules and 10 to the 6th power additional pentacene molecules. This may be accomplished by a combination of laser FM spectroscopy and either Stark or ultrasonic double-modulation, using the additional fact that in an inhomogeneously broadened line, the laser wavelength may be chosen such that only one impurity molecule is in resonance. Keywords: Ultrasensitive spectroscopy.
