In situ one-pot synthesis of graphitic carbon nitride quantum dots and its 2,2,6,6-tetramethyl(piperidin-1-yl)oxyl derivatives as fluorescent nanosensors for ascorbic acid
Ultrathin g-C3N4 nanosheets and fluorescent g-C3N4 quantum dots are simultaneously prepared via one-pot ethanol-thermal treatment in the presence of KOH.
