| titleOfInvention | Preparation method of core-shell structure quantum dot |
| abstract | The invention relates to a preparation method of a core-shell structure quantum dot, which belongs to the technical field of nanometer material preparation. The preparation method comprises the following steps of: preparing I-III-VI group nanometer crystal nucleus by using a method for injecting negative ion monomers by using a high temperature oil phase, and preparing one to three layers of II-VI group nanometer crystal shells by using a one-step coupled growth method so as to obtain the quantum dot which takes (CumaAg1-m)x(InnGa1-n)ySz as the nucleus and ZnSe/ZnSepS1-p/Zns as nanometer crystal shells. In the preparation method, the regulation and control on the sizes of nanometer particles are realized through means of changing the concentration and temperature of a system ligand, the proportion of reactants and the like; and the prepared quantum dot has the characteristics of high fluorescent efficiency, good stability, simpleness and convenience for operation, good repeatability, low cost and low toxicity. The prepared quantum dot does not contain heavy metals, not only can meet the requirements of biological markers and biological detection and application, but also provides an excellent luminescent material for illumination, displayers and the like. |
