Abstract: A present application provides a light-emitting device and a method of manufacturing the same. The light-emitting device includes an anode, a hole transport layer, a light-emitting layer, an electron transport layer, and a cathode all laminated together. The hole transport layer is treated with a high boiling point polar solution to reduce a Coulomb force of the hole transport layer. The light-emitting device of the present application can improve light-emitting efficiency of the light-emitting device.

Abstract: A light-emitting device and a manufacturing method thereof are provided. The light-emitting device includes an anode, a luminous layer, and a cathode, which are disposed in a stacked manner, and a material of the luminous layer includes a perovskite material. A first transport layer is further provided between the luminous layer and the anode, and the first transport layer is configured to transport holes. Alternatively, a second transport layer is further provided between the cathode and the luminous layer, and the second transport layer is configured to transport electrons.

Abstract: An embodiment of the present invention discloses a method of manufacturing a light-emitting device. In an embodiment of the present invention, a method of manufacturing a light-emitting device is provided. Because the electron transport layer is prepared by solution processing, compared with the traditional vacuum evaporation coating, it can use a simpler equipment and a simpler process, and have a higher material utilization rate, which effectively improves the preparation effectiveness of the light-emitting device.

Abstract: An electrode, a perovskite light-emitting diode and a preparing method thereof are provided by using a specific polymer-based surface modifier, PEIE and/or PEI, to modify carbon materials, so as to obtain an electrode with low work function, the electrode as a cathode of a perovskite light-emitting diode is more favorable for electrons injecting into the perovskite light-emitting layer.
