A perovskite nanocrystal particle light emitting body having a core-shell structure, a method of manufacturing the same, and a light emitting element using the same. The organic-inorganic hybrid perovskite nanocrystal particle emitter or metal halide perovskite nanocrystalline particle emitter having a core-shell structure includes a perovskite nanocrystal structure dispersible in an organic solvent, and a core-shell structure Of nanocrystalline grain structure. Accordingly, the perovskite nanoparticle luminescent material according to the present invention can form a shell with a material having a bandgap larger than that of the core, so that the exciton can be more easily confined to the core, and the perovskite nanopowder stable in the air, It is possible to prevent the core perovskite from being exposed to the air to improve the durability of the nanocrystals. |
