Carbon quantum dots: an emerging material for optoelectronic applications

Abstract

As an emerging class of luminescent nanomaterials, carbon quantum dots (CQDs) have recently shown enormous potentials for optoelectronic applications on account of their characteristic broad emission, tunable fluorescence emission, and high thermal stability, and low cytotoxicity. In this review, we will update the latest research progress achieved in CQDs, including their synthesis, optical properties, luminescence mechanism, and applications in optoelectronics. Mainly reviewed here are their room temperature phosphorescence, delayed fluorescence properties, as well as their optoelectronic applications including light-emitting diodes, lasing, solar cells, and photodetectors. Finally, current problems and challenges of CQDs-based optoelectronics applications are discussed with an eye on future development. We hope that this review will provide critical insights to inspire new exciting discoveries on CQDs from both fundamental and practical standpoints so that the realization of their potential in the optoelectronic areas can be facilitated.
