Abstract
We report on the photoluminescent (PL) properties of carbon nanodots (CNDs) doped with nitrogen and sulfur obtained by the pyrolytic carbonization of amino acids as precursors. Prepared CNDs exhibit stable PL emission under a wide variety of aqueous conditions. The results also provided the way to tune a PL intensity of CNDs by varying the amount of heteroatoms in precursors with a binary mixture of amino acids. The PL quantum yields of the obtained CNDs were determined to be from 0.079 to 0.571.
