摘要
As a kind of fluorescent nano material with good optical properties and low toxicity, carbon quantum dots have been developed into a new type of fluorescent probe, which can be used for the detection of heavy metal pollution in the environment. At present, the synthesis methods of carbon quantum dots have been mature, but the research reports on the factors affecting the fluorescence properties of carbon quantum dots are few. This paper, starting from the structure of the carbon quantum dots, focuses on the fluorescence characteristics of the dots, discusses the factors affecting the fluorescence performance of the dots, and compares the methods to improve the fluorescence intensity of the dots. The environmental application of carbon quantum dots is analyzed and prospected.
