Abstract

Nitrogen and sulfur co-doped green fluorescent carbon dots (G-CDs) with quantum yield (QY) of 28.26% were synthesized by hydrothermal method with p-phenylenediamine and thiosemicarbazone as precursors. The synthesized G-CDs exhibit good sensitivity and anti-interference ability for detecting copper ion (Cu2+) by fluorescence quenching (λex=390 nm, λem=535 nm) with a linear range of 20 to 200 μM and the limit of detection of 4.8 μM. This analytical method has been applied to detect Cu2+ of the local lake with good accuracy and recovery.
制备用于灵敏检测 Cu2+ 的高量子产率氮硫共掺杂碳点
以对苯二胺和硫代氨基甲酮为前驱体,通过水热法合成了氮和硫共同掺杂的绿色荧光碳点(G-CDs),其量子产率(QY)为 28.26%。合成的 G-CDs 在荧光淬灭(λex=390 nm,λem=535 nm)检测铜离子(Cu2+)时具有良好的灵敏度和抗干扰能力,线性范围为 20 至 200 μM,检测限为 4.8 μM。该分析方法已被用于检测当地湖泊中的 Cu2+,具有良好的准确性和回收率。
