Description
A simple one-pot synthetic strategy based on the hot injection methodology was adapted to prepare (photo)stable and green emissive colloidal CsPbBr3@CsPb2Br5 core@shell heteronanocrystals (HNCs). The photoactive core, specifically CsPbBr3 ternary metal halide nanocrystals, was homogeneously covered with an ultrathin CsPb2Br5 shell (ca. 2 nm), which confers them with long-term stability and a higher photoluminescence quantum yield. Astonishingly, this heterostructure enabled controlled halide exchange to yield unprecedented CsPbCl3@CsPb2Cl5 and CsPbI3@CsPb2I5 HNCs.
