| titleOfInvention | Boron-nitrogen co-doped fluorescent carbon quantum dot, preparation method and application of boron-nitrogen co-doped fluorescent carbon quantum dot in preparation of copper ion sensor |
| abstract | A boron-nitrogen co-doped fluorescent carbon quantum dot, a preparation method and application thereof in preparing a copper ion sensor belong to the technical field of metal ion detection. Mixing glucose, dicyanodiamine and boric acid, and performing heat treatment on the mixture to obtain a boron-nitrogen co-doped carbon material; and adding the boron-nitrogen co-doped fluorescent carbon quantum dot into deionized water, filtering to remove insoluble impurities to obtain a boron-nitrogen co-doped carbon quantum dot aqueous solution, and drying in vacuum to obtain the boron-nitrogen co-doped fluorescent carbon quantum dot. The boron-nitrogen co-doped fluorescent carbon quantum dot prepared by the method shows good selectivity, after copper ions are added into a boron-nitrogen co-doped fluorescent carbon quantum dot aqueous solution, the fluorescence of the boron-nitrogen co-doped fluorescent carbon quantum dot is obviously quenched, and the addition of other ions does not cause the fluorescence quenching of the boron-nitrogen co-doped fluorescent carbon quantum dot. Therefore, the boron-nitrogen co-doped fluorescent carbon quantum dot can be used for detecting copper ions and used for preparing a copper ion sensor. |
