英文摘要	carbon quantum dots (c-dots) are promising fluorescence probes for applications in metal ion detection, biosensing and bioimaging and so on. in this study, water soluble carbon nanodots were synthesized through a simple one-step heat treatment of ethylene glycol solution. in the present preparation, the c-dots may be formed through the hydration, crosslinking and carbonization processes. the synthesized c-dots show a green luminescent emission under ultraviolet excitation, which can be used for the detection of ag+ ions. interestingly, in a different way to the usual quenching effects of metal ions on the fluorescence of c-dots, ag+ exhibited an enhancement effect on the photoluminescence of c-dots, which can be attributed to the reduction of ag+ to silver nanoclusters (ag-0) on the surface of the c-dots. based on the linear relationship between fluorescence intensity and concentration of ag+ ions, the prepared c-dots can be used for sensitive and selective detection of silver ions in environmental water with a limit of detection of 320 nm and a linear range of 0-90 mu m.
