Fifty-four Eucommia ulmoides leaves were subjected to a hydrothermal technique to synthesize carbon dots (CDs) of 3.55 ± 1.45 nm size. The nanomaterial possessed excellent stability and strong fluorescence emission (φf 42.3%). In a neutral buffer solution, the fluorescence signals of CDs solution were enhanced by aluminium ion without interference from other ions. Degree of enhancement correlated linearly with the Al3+ content in the range 0.01–2.5 mM. Response of this method was fast and sensitive (detection limit was 23 nM). The CDs performed successfully as a sensitive sensor for trace Al3+ determination in water samples, and satisfactory results were obtained.

用荧光法合成用于水中 Al3+ 传感的碳点

54 片杜仲叶采用水热技术合成 3.55 ± 1.45 nm 大小的碳点 (CD)。该纳米材料具有优异的稳定性和强荧光发射(φ f 42.3%)。在中性缓冲溶液中,铝离子增强了CDs溶液的荧光信号,不受其他离子的干扰。增强程度与范围 0.01–2.5 mM 内的 Al 3+含量呈线性相关。该方法的响应快速且灵敏(检测限为 23 nM)。CDs 成功地用作测定水样中痕量 Al 3+的灵敏传感器,并获得了令人满意的结果。
