摘要：

By a series of characterization of quantum dots and their films for different synthesis conditions and preparation parameters, the synthesis conditions of cesium lead bromide quantum dots and the quantum dots film preparation parameters are optimized. The effects of reaction temperature and reaction time on the properties of CsPbBr3 perovskite quantum dots were studied by thermal injection. The quantum dot samples of perovskite under different synthetic conditions were obtained and characterized. Then all CsPbBr3 quantum dot samples were prepared into thin films to explore its photoluminescence properties. When the reaction temperature is 180℃, the reaction time is 5 s, the quantum dot size is 9 nm, reaching the minimum value. With the spin speed of 3 000 r/min, the annealing temperature of 80℃ and the annealing time of 10 min, the CsPbBr3 quantum dots film has the strongest photoluminescence intensity. The optimum synthesis conditions of CsPbBr3 quantum dots and the CsPbBr3 quantum dots film preparation conditions were obtained. © 2019, Science Press. All right reserved.
