Phonon-assisted anti-Stokes fluorescence has been observed in GaN film grown on Si (111) substrate. The donor-acceptor pairs and bound excitons have played primary roles in the generation of anti-Stokes fluorescence.
Resonance fluorescence of a single InGaAs/GaAs quantum dot enables us to show direct evidence of population up-conversion to an excited state in a quantum dot, which we attribute to single-acoustic-phonon processes at low temperature.
Photonic crystal nanocavities with resonances in the visible and near-IR couple easily to nearby fluorescent molecules. Photoluminescence spectra demonstrate that the cavities, fabricated in a gallium phosphide membrane, have quality factors up to 11,000.
