Mena et al. demonstrated optically detected coherent control of photoexcited pentacene triplet spins at room temperature in a molecular crystal and a thermally evaporated film.

Key Results

  • Observed room-temperature Rabi oscillations with photoluminescence contrast exceeding .
  • Retained microsecond-scale coherence in both bulk-crystal and thin-film realizations.
  • Demonstrated a molecular spin–optical interface aimed primarily at quantum sensing and imaging.
