Synthesis of Photoluminescent Carbon Nanodots and their Inarching with Quercetin

Carbon nanodots (CDs) have been synthesized by chemical oxidation of C 6 H 12 O 6 in NaOH solution . The as-prepared CDs possess strong blue luminescence.KH560 serve as coupling agent to modify the quantum dots by the method of ultrasound reaction .Finally the obtained C-dots powder have been successfully grafted with quercetin,which is one kind of flavone .This process made the drug have better thermal stability.
