Abstract:
本发明提供一种新颖的发光元件、发光效率良好的发光元件、色纯度良好的发光元件。本发明是一种发光元件，包括：阳极、阴极以及形成在所述阳极与所述阴极之间的包含发光物质的层，其中，所述包含发光物质的层包括发光层、第一电子传输层以及第二电子传输层，所述发光层与所述第一电子传输层彼此接触，所述第一电子传输层与所述第二电子传输层彼此接触，所述第一电子传输层及所述第二电子传输层位于所述发光层与所述阴极之间，所述发光层包含以通式(SA)MX3、通式(LA)2(SA)n-1MnX3n+1或通式(PA)(SA)n-1MnX3n+1表示的金属卤化物钙钛矿材料，所述第一电子传输层包含第一电子传输材料，并且，所述第二电子传输层包含第二电子传输材料。
Abstract(English):

A novel light-emitting element is provided. A light-emitting element with high emission efficiency is provided. A light-emitting element with high color purity is provided. The light-emitting elementincludes an anode, a cathode, and a layer including the light-emitting substance between the anode and the cathode. The layer including the light-emitting substance includes a light-emitting layer, afirst electron-transport layer, and a second electron-transport layer. The light-emitting layer and the first electron-transport layer are in contact with each other. The first electron-transport layer and the second electron-transport layer are in contact with each other. The first electron-transport layer and the second electron-transport layer are positioned between the light-emitting layer andthe cathode. The light-emitting layer includes a metal-halide perovskite material represented by General Formula (SA)MX3, General Formula (LA)2(SA)n-1MnX3n+1, or General Formula (PA)(SA)n-1MnX3n+1. The first electron-transport layer includes a first electron-transport material, and the second electron-transport layer includes a second electron-transport material.
