次氯酸已被广泛用作工业和家庭消毒剂，但大量实验表明，过量使用次氯酸会导致多种人类疾病。然而，目前还没有一种有效的替代方法来检测高选择性和高灵敏度的ClO(-)离子。本文采用一锅水热法合成了氮氟共掺碳量子点。它们在465 nm处有一个激发峰，在506 nm处有一个强发射峰，它们在氯化钠水溶液或不同pH值的溶液中表现出良好的荧光稳定性。NFCDs被成功地用作检测ClO的荧光探针。NFCDs的荧光强度可被ClO-非常迅速地猝灭(
Hypochlorous acid has been used widely as a disinfectant in industrial and home applications, but numerous experiments suggest that excessive use of hypochlorous acid can lead to a variety of human diseases. However, an effective alternative method to detect ClO(- )ions with high selectivity and sensitivity does not yet exist. Herein, nitrogen-fluorine-codoped carbon quantum dots (NFCDs) were synthesized by a one-pot hydrothermal method. They displayed an excitation peak at 465 nm and a strong emission peak at 506 nm and their fluorescence demonstrated excellent stability in NaCl aqueous solution or the solution with varied pH values. The NFCDs were successfully used as fluorescent probes for ClO- detection. The fluorescence intensity of NFCDs could be quenched by ClO- very quickly (
