Perovskite quantum dot for enhancing core-shell anchoring, preparation method and application

The invention provides a perovskite quantum dot for enhancing core-shell anchoring and a preparation method and application thereof, and the preparation method comprises the following steps: mixing a porous material, a benign solvent and a perovskite raw material to obtain a mixture, and carrying out precipitation treatment after mixing to prepare a porous material with a perovskite crystal nucleus, and carrying out heating treatment to prepare the perovskite quantum dot for enhancing core-shell anchoring. According to the invention, through a two-step method of anchoring first and then growing, firm connection is formed between perovskite crystal lattices and the porous material through chemical bonding, and the effects of stabilizing the crystal structure and improving the stability are achieved. Meanwhile, the method has universality, the process of pre-embedding the crystal nucleus through a solution method is suitable for various solvents, and large-scale production is easy to realize. 本发明提供了一种增强核壳锚定的钙钛矿
