This invention proposes a simple and easy-to-operate method for preparing core-shell quantum dots that suppress Auger recombination, and develops Mn-doped CsPbCl3@Cs4PbCl6 core-shell nanocrystals. The Auger suppression performance was studied using wavefunction engineering. The method includes the following steps: ① Synthesizing CsPbCl3 nanocrystals via thermal injection. ② Forming a Cs4PbCl6 shell nanocrystal on the CsPbCl3 nanocrystals. An oleic acid solution containing Cs is added to the CsPbCl3 nanocrystals; Cs ions tend to react with free Pb ions, and the Cs4PbCl6 shell nanocrystals grow epitaxially on the surface of the CsPbCl3 core nanocrystals. ③ Injecting a MnCl2 precursor into the pre-synthesized core-shell nanostructure at room temperature yields highly efficient Mn-emitting nanocrystals with promising applications in optoelectronics, generating significant social and economic benefits.
