Abstract	In this paper, the highly emissive CsPbI3 perovskite quantum dots (QDs) with good stability are successfully synthesized with trioctylphosphine (TOP) as surface ligands. Furthermore, a facile and fast anion exchange is realized at the interface of nonpolar CsPbX3 solution and aqueous hydrohalic acid. Perovskite QDs can react with halide ions at room temperature swiftly to adjust their ratio of halogens and then the emission. The photo-luminescence (PL) can be tuned over wide spectral region (423.0-670.5 nm). And this work also provides a fast avenue to tune the emission of halide perovskite QDs.
