| Outline of Final Research Achievements |
Surface-emitting microcavities are fabricated using thiophene/phenylene co-oligomer (TPCO) crystals sandwiched between distributed Bragg reflector (DBR) mirrors. Their angle-resolved photoluminescence spectra with anti-crossing energy dispersions demonstrate the formation of exciton-polaritons resulting from strong coupling between cavity-photons and excitons under optical excitation. Towards electrically excited polariton lasing, p/n-junction organic electroluminescence (EL) devices are fabricated with TPCO films on a DBR substrate. Their angle-resolved EL spectra also suggest the formation of exciton-polaritons under electrical excitation.
