Abstract: A light-emitting layer for a halide perovskite light-emitting device, a method for manufacturing the same and a perovskite light-emitting device using the same are disclosed. The light-emitting layer can be manufactured by forming a first nanoparticle thin film by coating, on a member, a solution comprising halide perovskite nanoparticles having a halide perovskite nanocrystalline structure. Thereby, a nanoparticle light emitter has therein a halide perovskite having a crystal structure in which FCC and BCC are combined; and can show high color purity. In addition, it is possible to improve the luminescence efficiency and luminance of a device by making perovskite as nanoparticles and then introducing the same into a light-emitting layer.
