摘要

以柠檬酸为碳源制备碳量子点（CQDs）'所得碳量子点被394 nm的光激发后在484 nm处有较强的荧光发射'最大吸收波长为482 nm的日落黄能强烈猝灭碳量子点的荧光。基于该现象'发展了一种以碳量子点为荧光探针测定日落黄的分析方法'并探讨了荧光猝灭机理。在选定的实验条件下'该分析方法的线性检测范围为0.1~100 mol/L'检出限（3

）为0.051 mol/L。

Abstract

Water-soluble carbon quantum dots (CQDs) were prepared by using citric acid as carbon source. The obtained CQDs showed a strong emission at the wavelength of 484 nm

with an optimum excitation of 394 nm. Sunset yellow with maximum absorption wavelength at 482 nm could selectively quench the fluorescence of CQDs. Based on this principle

a fluorescent probe was developed for sunset yellow determination. Furthermore

the quenching mechanism of the CQDs was elucidated. A linear relationship was found in the range of 0.1-100 mol/L sunset yellow with the detection limit (3

) of 0.051 mol/L. Satisfactory results were achieved when the method was submitted to the determination of sunset yellow in liquid samples.
