摘要： A perovskite film and a method of manufacturing same are provided. By adding a surfactant during a process of manufacturing a perovskite solution and adopting a coating method during a process coating the perovskite solution onto a substrate, a flatness of the perovskite film is effectively improved, and a thickness of the perovskite film is uniform. Therefore, the perovskite film becomes more smoothly and has better compactness. Thus, the present invention also has advantages of simple manufacturing process, reduced cost, and suitable for large-scale industrial production.

摘要： A method of preparing a film and a light-emitting device are disclosed. The method includes: providing at least one gas-phase source above a substrate, the at least one gas-phase source made of materials comprising a perovskite material; and controlling an evaporation rate of the at least one gas-phase source to form a perovskite film. In the method provided by the present invention, a perovskite light-emitting layer is prepared by gas-phase source evaporation coating without an organic solvent, which avoids miscibility between the organic solvent and other layers and improves compatibility between the perovskite material and other film materials, thereby realizing the low preparation cost and the simple preparation process.
