In this work, we introduce a high\u2010temperature vapor\u2010phase deposition for the controlled synthesis of CsPbI\n                    <jats:sub>3<\/jats:sub>\n                    \/CsPbBr\n                    <jats:sub>3<\/jats:sub>\n                    and CsPb(Br\/I)\n                    <jats:sub>3<\/jats:sub>\n                    \/CsPbBr\n                    <jats:sub>3<\/jats:sub>\n                    heterostructure NCs encapsulated within a robust SiO\n                    <jats:sub>2<\/jats:sub>\n                    matrix. This method spatially separates the CsPbBr\n                    <jats:sub>3<\/jats:sub>\n                    shell precursor from the preformed iodine\u2010rich core in the vapor phase, effectively suppressing undesirable halide diffusion during high\u2010temperature processing at 700\u00b0C. By leveraging the strong Br\u2500Cs\/Pb interactions, the CsPbBr\n                    <jats:sub>3<\/jats:sub>\n                    vapor promotes preferential interfacial deposition on CsPbI\n                    <jats:sub>3<\/jats:sub>\n                    or CsPb(Br\/I)\n                    <jats:sub>3<\/jats:sub>\n                    cores. The resulting NCs display highly efficient red emission, achieving a PLQY as high as 85%. Furthermore, benefiting from the dual protection of the SiO\n                    <jats:sub>2<\/jats:sub>\n                    matrix and the heterostructure, these red\u2010emitting materials exhibit
