The Suk-Won Choi Research Group at Kyung Hee University conducts basic and applied research in organic optical materials, exploring their applications in diverse fields such as displays, lasers, light-emitting diodes, lighting, and sensors. Recently, the group has actively focused on circularly polarized luminescent materials, high-purity luminescent materials with narrow full-width at half-maximum (FWHM), organic-inorganic composite luminescent materials, and energy harvesting materials/devices.

경희대학교 최석원 연구그룹은 유기 광학 재료의 기초 및 응용 연구를 수행하며, 디스플레이, 레이저, 발광 다이오드, 조명 및 센서와 같은 다양한 분야에서의 응용을 탐구합니다. 최근에는 원형 편광 발광 재료, 반치폭(FWHM)이 좁은 고순도 발광 재료, 유무기 복합 발광 재료, 에너지 하베스팅 재료/장치에 적극적으로 초점을 맞추고 있습니다.
