Abstract:

Using highly efficient Fluorescence excitation spectroscopy of individual pentacene molecular impurities in p-terphenyl crystals, we have observed that some pentacene defects exhibit spontaneous spectral jumps in their resonance frequency at 1.5 K, with a jump rate independent of laser power. In addition, the low-power limiting linewidth for single pentacene absorbers reaches the lifetime limit of 7.8 MHz at 1.5 K.
