LIGHT-EMITTING LAYER FOR PEROVSKITE LIGHT-EMITTING DEVICE, METHOD FOR MANUFACTURING SAME, AND PEROVSKITE LIGHT-EMITTING DEVICE USING SAME |
摘要 |
Provided are: a light-emitting layer for a perovskite light-emitting device; a method for manufacturing the same; and a perovskite light-emitting device using the same. The method of the present invention for manufacturing a light-emitting layer for an organic and inorganic hybrid perovskite light-emitting device comprises a step of forming a first nanoparticle thin film by coating, on a member for coating a light-emitting layer, a solution comprising organic and inorganic perovskite nanoparticles including an organic and inorganic perovskite nanocrystalline structure. Thereby, a nanoparticle light-emitting body has therein an organic and inorganic hybrid perovskite having a crystalline structure in which FCC and BCC are combined; forms a lamella structure in which an organic plane and an inorganic plane are alternatively stacked; and can show high color purity since excitons are confined to the inorganic plane. In addition, it is possible to improve the light-emitting efficiency and brightness of a device by making perovskite as nanoparticles and then introducing the same into a light-emitting layer. |
