Fluorescent Carbon Dots

Fluorescent carbon dots (CDs) as a new-type kind of zero-venami material have attracted growing interest. Herein, we developed a novel and convenient method to prepare dual emission nitrogen-doped carbon dots (N-CDs). Under ultraviolet (UV) light, N-CDs show blue and orange fluorescence centered at 435[Formula: see text]nm and 595[Formula: see text]nm, respectively. Because the two emission peaks of N-CDs exhibit different sensitivity to dopamine (DA), the N-CDs can serve as ratiometric fluorescent probes for DA measurement. The ratio ([Formula: see text]/[Formula: see text]) exhibits good linear relationship with DA concentration within the scope of 45–80[Formula: see text][Formula: see text]M. The quenching mechanism of N-CDs toward DA is also proposed, and it is suggested that the quenching may start because by the electrostatic interaction between N-CDs and DA.
