Recent Advances of Carbon Dot-Based Light-Emitting Diodes

Carbon dots (CDs), with abundant raw materials on earth, have become a new-type of luminescent materials and received great attention for their excellent merits such as low cost, low toxicity, strong photo stability, good biocompatibility, and high photoluminescence (PL). It's superior to traditional fluorescent organic dyes and luminescent inorganic quantum dots (QDs).
