Abstract

We report a facile two-step strategy to construct well-shaped PMBA@CsPbBr₃ nanoparticles, with this strategy involving combining in situ adsorption and controlled polymerization. The morphological evolution process and mechanism of formation of the nanoparticles were demonstrated, and the nanoparticles showed high sensitivity to corrosive acid gas. This work has provided an effective approach for fabricating well-structured perovskite-based nanocomposites.
