摘要：

Herein, bright green luminescent graphitic carbon nitride quantum dots (GCNQDs) doped with oxygen and sulfur are prepared simply by microwave treatment of citric acid and thiourea. The as -obtained GCNQDs show excitation wavelength and pH dependent luminescence behaviors in the visible range. Besides, the GCNQDs exhibit high fluorescence quantum yield (31.67%), strong resistance to the interference of high ionic strength environment, and good biocompatibility as demonstrated by the cell viability assay. Thus, the resulting GCNQDs can be used as a promising fluorescent probe for HeLa cell imaging with low cytotoxicity, and have great potential in bioanalysis and related fields. (C) 2015 Elsevier B.V.
