The invention relates to the technical field of nanomaterials, and discloses a green light-excited carbon quantum dot, comprising the following preparation method: neutral red and citric acid monohydrate are dissolved in water, and the obtained dark red solution is reacted at 160-180° C. After 4-6 h, the reacted purple solution was centrifuged, and the supernatant was dialyzed with a dialysis bag to obtain carbon quantum dots excited by green light. The carbon quantum dots excited by green light of the present invention can enable plants to utilize green light for photosynthesis, improve the ability of plants to utilize green light, and have the advantages of simple preparation, good water solubility, good biocompatibility and no toxic and side effects. |
