Abstract: Provided are an organic-inorganic-hybrid perovskite nanocrystal particle light-emitter having a two-dimensional structure, a method for producing the same, and a light emitting device using the same. The organic-inorganic-hybrid perovskite nanocrystal particle light-emitter having a two-dimensional structure comprises an organic-inorganic-hybrid perovskite nanocrystal structure having a two-dimensional structure which can be dispersed in an organic solvent. Accordingly, the nanocrystal particle light-emitter comprises an organic-inorganic-hybrid perovskite nanocrystal having a crystal structure combining FCC and BCC; forms a lamellar structure where organic planes and inorganic planes are accumulated in an alternating manner; and can exhibit high color purity by confining excitons in the inorganic planes. In addition, since the exciton diffusion distance decreases and exciton binding energy increases, it is possible to prevent exciton annihilation caused by thermal ionization and delocalization of charge carriers, such that the nanocrystal particle light-emitter can have high luminescence efficiency at room temperature.
