N/S/P-co-doped carbon dots with tunable luminescence properties were synthesized from cucumber juice, and used as fluorescent probes for Hg2+ detection.
A ratiometric fluorescent N,S co-doped carbon dots (N,S-CD) probe for ClO− has been facilely obtained via a one-step hydrothermal method.
In this work, novel carbon dots codoped with nitrogen and sulfur (NSCDs) were used as fluorescent probes to detect Cr3+.
