Quantum dots are a tiny semiconductor nanocrystal and are considered to be one of the most important cornerstones in modern optoelectronics. The novel copper indium sulfide (CuInS2) quantum dots used herein are water-soluble quantum dots synthesized by hydrothermal methods. The quantum dot does not need to use an organic solvent in the synthesis process, and the composition does not contain heavy metal elements such as cadmium and lead, and satisfies the requirements of current environmentally friendly type. The performance study of the prepared quantum dot materials shows that it has good fluorescence intensity and good light stability. Therefore, this new type of quantum dot material has very applicable application value and broad application prospects.
