Abstract
Nitrogen-doped carbon nanodots (CDs) were prepared via the solvothermal method, using urea and triethylene glycol as the starting materials. The as-prepared CDs had individual diameters of approximately 100 nm and werein clusters of different sizes. The surface composition and optical properties of the as-prepared CDs were characterized.They exhibited multicolor emission properties in the visible range when excited with a wide wavelength range. Theaqueous solution of the CDs was used in highly sensitive tartrazine determination. The fluorescence quenching of theCDs was in a linear relationship with the concentrations of tartrazine in the range of 0.5–30.0 µM. The detection limitof the assay was 0.18 µM. Acceptable recovery results were obtained via spike-recovery experiments on cookie samples.
