A light emitting device of the present invention comprises: an exciton buffer layer in which a first electrode, a conductive layer disposed on the first electrode and comprising a conductive material, and a surface buffer layer containing fluorine-based material having lower surface energy than the conductive material are sequentially deposited; a light-emitting layer disposed on the exciton buffer layer and containing a perovskite light-emitter; and a second electrode disposed on the light-emitting layer. Accordingly, a perovskite is formed with a combined FCC and BSS crystal structure in a nanoparticle light-emitter. The present invention can also form a lamellar or layered structure in which an organic plane and an inorganic plane are alternatively deposited; and an exciton can be bound by the inorganic plane, thereby being capable of expressing high color purity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Perovskite light emitting device containing exciton buffer layer and method for manufacturing same","description":"Provided are a perovskite light emitting device containing an exciton buffer layer, and a method for manufacturing the same.
