Carbon quantum dot and preparation method thereof |
| abstract |
The application provides a carbon quantum dot and a preparation method thereof. The preparation method comprises the following steps: s1, mixing the precursor with an organic solvent to prepare precursor dispersion liquid; s2, performing ultrasonic treatment and/or microwave treatment on the precursor dispersion liquid at normal pressure to obtain a carbon quantum dot solution; s3, purifying the carbon quantum dot solution to obtain carbon quantum dots; wherein the precursor comprises a plant. The preparation method has short time, easy process control and good repeatability; compared with the conventional high-temperature heating method, the prepared carbon quantum dots have higher efficiency and narrower half-peak width. |
