Embodiment 1
[0067] The present invention provides a preparation method of CdSe / CdS core-shell structure nanosheets, the preparation method includes the following steps:
[0068] (1) Take 340 mg of cadmium myristate powder and 20 mg of selenium powder prepared in advance and dissolve them in ODE, vacuum at 95°C for a certain period of time to remove water and oxygen impurities in the reaction system, and then heat the reaction system to 240°C . During the heating process, CdSe nucleated, and 70 mg of cadmium acetate powder was added at 195°C, and the longitudinal growth of crystal nuclei was inhibited by the addition of acetate to form a flake morphology. Finally, centrifuge the prepared solution at 5000 rpm for 10 minutes, and the solid obtained is the CdSe nanosheet;
[0069] (2) Dissolve 480mg of cadmium acetate in 2mL ODE, 340uL oleic acid, and 11mg sulfur powder in 3ml ODE respectively to prepare precursors and then mix;
[0070] (3) Add 1mL CdSe nanosheet solution with an optical density ...
