Optical Spectroscopy of Single Impurity Molecules in Solids
W. E. Moerner, Thomas Basché
Abstract Optical spectroscopy of a single impurity molecule provides the first truly local probe of host–guest interactions in doped solids. In conventional optical high‐resolution experiments with many molecules only ensemble averages of the microscopic parameters can be obtained. In the single‐molecule regime, the exquisite sensitivity of an individual dopant molecule to both the local environment and to external perturbations has been exploited in recent experiments to reveal a wealth of fascinating novel phenomena such as spectral diffusion in crystals and polymers, optical modification of a single impurity molecule (spectral hole‐burning), local field measurements at the site of a single impurity molecule, and quantum optics in a solid.
