Metal pollution in water sources due to modernization is a human health and environmental problem. Therefore, the highly fluorescent boron- and nitrogen-doped and nitrogen-doped carbon quantum dots (B,N-CQDs and N-CQDs, respectively) were synthesized and investigated to be used as a fluorescence sensor for metal ion detection. In this study, the synthesized B,N-CQDs and N-CQDs had an average size of 4-6 nm and 3-4 nm, respectively. The B,N-CQDs presented high sensitivity as 0.0090, 0.0086 and 0.0091 units per micromolar for Cr, Cu and Fe, respectively, whereas the N-CQDs showed sensitivity as 0.0047, 0.0102, 0.0095 and 0.0121 units per micromolar for Cr, Cu, Fe and Ni, respectively. In the concentration range of 10-80 μM, the detection limits of B,N-CQDs and N-CQDs were found to be in the range of 13.9-65.5 μg/L and 14.9-38.3 μg/L, respectively. The result of the study clearly indicates that B,N-CQDs and N-CQDs can be seen as metal ion sensing devices with high sensitivity and low cost.
现代化导致的水源金属污染是一个人类健康和环境问题。因此，合成并研究了高荧光的硼氮共掺杂和氮掺杂碳量子点（分别为B，N-CQDs和N-CQDs），以用作金属离子检测的荧光传感器。在本研究中，合成的B，N-CQDs和N-CQDs的平均尺寸分别为4-6nm和3-4nm。B，N-CQDs对Cr、Cu和Fe的灵敏度分别为每微摩尔0.0090、0.0086和0.0091单位，而N-CQDs对Cr、Cu、Fe和Ni的灵敏度分别为每微摩尔0.0047、0.0102、0.0095和0.0121单位。在10-80μM的浓度范围内，发现B，N-CQDs和N-CQDs的检测限分别在13.9-65.5μg/L和14.9-38.3μg/L范围内。研究结果清楚地表明，B，N-CQDs和N-CQDs可被视为具有高灵敏度和低成本的金属离子传感装置。
