Photon Antibunching in the Fluorescence of a Single Dye Molecule Trapped in aSolid

摘要

The correlation between fluorescence photons emitted by an optically pumpedsingle molecule of pentacene in a p-terphenyl host has been investigated at short times. The correlation function shows photon antibunching, an unique feature of nonclassical radiation field, which decreases if two molecules rather than one are pumped at the same time. The peculiarities of the correlation function for a three-level molecule are discussed and the theoretical description outlined.
