Cyan color-emitting nitrogen-functionalized carbon nanodots (NFCNDs) from and their catalytic reduction of organic dyes and fluorescent ink applications.

The present study reports the synthesis of nitrogen-functionalized carbon nanodots (NFCNDs) by a low-cost hydrothermal method using the leaf extract of as a novel carbon precursor. The synthesized NFCNDs were characterized by diverse spectroscopic techniques. The optical properties of N-CNDs were analyzed by UV-visible and fluorescence spectroscopic studies.
