Abstract

We have developed a facile ultrasound-assisted route to synthesize N/S/P co-doped carbon dots (N/S/P-CDs) in an alkaline solution at room temperature. They demonstrate brightly luminescent and thermo-tunable fluorescence properties and show ultra-high sensitivity for the detection of TC in milk via the inner filter effect (IFE) of a two-way matching strategy.
