초록/요약
A cost-effectiveand environmentally friendly approach is proposedfor producing N- and S-codoped multicolor-emission carbon dots (N-and S-codoped MCDs) at a mild reaction temperature (150 & DEG;C) andrelatively short time (3 h). In this process, adenine sulfate actsas a novel precursor and doping agent, effectively reacting with otherreagents such as citric acid, para-aminosalicylicacid, and ortho-phenylenediamine, even during solvent-freepyrolysis. The distinctive structures of reagents lead to the increasedamount of graphitic nitrogen and sulfur doping in the N- and S-codopedMCDs. Notably, the obtained N- and S-codoped MCDs exhibit considerablefluorescence intensities, and their emission color can be adjustedfrom blue to yellow. The observed tunable photoluminescence can beattributed to variations in the surface state and the amount of Nand S contents. Furthermore, due to the favorable optical properties,good water solubility and biocompatibility, and low cytotoxicity,these N- and S-codoped MCDs, especially green carbon dots, are successfullyapplied as fluorescent probes for bioimaging. The affordable and environmentallyfriendly synthesis method employed to create N- and S-codoped MCDs,combined with their remarkable optical properties, offers a promisingavenue for their use in various fields, particularly in biomedicalapplications.
