| 中文摘要 | chromium(vi) [cr(vi)] is considered as a severe environmental pollutant, due to its highly toxic and carcinogenic properties. therefore, low cost, highly sensitive sensors for the determination of cr(vi) are highly demanded. it is well-known that highly luminescent carbon dots (cds) have been successfully applied as fluorescent nanosensors for ph, ions, and molecular substances. in the present work, we have demonstrated an on-off fluorescent cd probe for detecting cr(vi) based on the inner filter effect (ife) because the absorption bands of cr(iv) fully covered the emission and excitation bands of cds. this cd-based nanosensor provides obvious advantages of simplicity, convenience, rapid response, high selectivity, and sensitivity, which have potential application for the detection of cr(vi) in the environmental industry. in addition, because cr(vi) can be reduced to low valent chromium species easily by reductant, resulting in the elimination of the we and recovery of cd fluorescence, the cd-cr(vi) mixture could behave as an off-on type fluorescent probe for reductant. we employed ascorbic acid (aa) as an example molecule to demonstrate this off-on type fluorescent probe. |
