| titleOfInvention | A carbon quantum dot with broad-spectrum ultraviolet absorption |
| abstract | The invention provides a carbon quantum dot with broad-spectrum absorption of ultraviolet light: the surface of the carbon quantum dot is grafted with a group of one type and a group of two types, and the group of one type contains C=O, C-OH, and C-NH At least one, the second type of group has a nitrogen-containing heterocyclic ring in a conjugated structure. The conjugated structure of the two types of groups grafted on the surface of the carbon quantum dot provided by the present invention has π electrons, and the chemical bonds in the type of groups grafted on the surface of the carbon quantum dots, such as C=O, C ‑OH, C‑NH, etc., produce conjugation to form n‑π*, resulting in strong UVB absorption at 280–320nm. |
