The research interests of Dong's group include developing and synthesizing novel nanomaterials and elucidating their photophysical and electronic properties for photonics, energy, and photocatalysis applications. Semiconductor nanocrystal Quantum Dots (QDs) possessing superb optical properties such as tunable narrow-band emission, high luminescence efficiency, and solution processability are highly suitable for the next-generation materials of novel photonics and energy applications. Research in the Dong group at the University of Oklahoma focuses on developing and synthesizing new QDs with exquisite size, shape, and surface control and studying their optical and electronic properties at the single particle level. Our group also aims to exploit the advanced QD material to enable cutting-edge photonics devices such as ultra-fast single photon sources.
