Synthesis,Properties and Applications of the Fluorescent Carbon Dots

As a novel carbon nano-luminescent material, fluorescent carbon dots are considerably concerned because of their excellent biocompatibility, good luminescence performance, simple synthesis process, low cost and so on, compared with conventional luminescent materials. They are potential candidates for the application in biological fluorescence calibration, medical sensors, phototheranostics and light-emitting devices. The new achievements of the synthesis method, fluorescence mechanism and applications of fluorescent carbon dots are demonstrated in this paper.
