This work reports the synthesis of nitrogen and sulfur co-doped carbon dots (NS-CDs) via a one-step facile microwave-assisted pyrolysis using citric acid and thiourea as the carbon precursor and dopant, respectively. The resultant NS-CDs were found to be uniform in size and can be dispersed in aqueo...
