摘要：

The carbon quantum dots (CDs) based on carbonization of citric acid and tris(hydroxymethyl)aminome thane (Tris) in glycerinum as fluorescent probes for highly sensitive and selective detection of Fe3+ have been developed. The obtained CDs exhibit an excitation-dependent fluorescence behavior. The most intense fluorescence appears under 340 nm excitation and has a maximum emission peak at 414 nm. The CDs can keep good fluorescence intensity in a wide pH values from 2 to 11. The CDs can be used as highly sensitive and selective detection fluorescent probe of Fe3+, even in real sample analysis the CDs fluorescent probes can be used. (C) 2018 Elsevier B.V.
