Provided are a perovskite film and method for manufacturing the same, a perovskite electroluminescent device and method for manufacturing the same, and a display device, which belongs to the technical field of displaying. The perovskite film comprises a crystalline perovskite and a halogenated amine ligand grafted onto the crystalline perovskite. Since the perovskite film comprises the halogenated amine ligand, the surface of the perovskite film is smooth, and the surface coverage of the crystalline perovskite is high without significant void defects. Meanwhile, the perovskite film also has a high fluorescence quantum yield due to the halogenated amine ligand comprised in the perovskite film.
本发明提供了一种过氧化物薄膜及其制造方法、一种过氧化物电致发光装置及其制造方法以及一种显示装置,属于显示技术领域。该过氧化物薄膜包括晶体过氧化物和接枝到晶体过氧化物上的卤化胺
配体。由于包晶薄膜包含卤化胺
配体,因此包晶薄膜表面光滑,晶体包晶的表面覆盖率高,没有明显的空隙缺陷。同时,由于包晶膜中含有卤化胺
配体,包晶膜还具有较高的荧光量子产率。
