摘要
Provided are a core-shell structured perovskite nanocrystalline particle light-emitting body, a method of preparing the same, and a light emitting device using the same. The core-shell structured organic-inorganic hybrid perovskite nanocrystalline particle light-emitting body or metal halide perovskite nanocrystalline particle light-emitting body is able to be dispersed in an organic solvent, and has a perovskite nanocrystal structure and a core-shell structured nanocrystalline particle structure. Therefore, in the perovskite nanocrystalline particle light-emitting body of the present invention, as a shell is formed of a substance having a wider band gap than that of a core, excitons may be more dominantly confined in the core, and durability of the nanocrystal may be improved to prevent exposure of the core perovskite to the air using a perovskite or inorganic semiconductor, which is stable in the air, or an organic polymer.
