| titleOfInvention | LED based on two-dimensional perovskite single crystal and preparation method thereof |
| abstract | The invention provides an LED based on a two-dimensional perovskite single crystal and a preparation method thereof. The two-dimensional perovskite single crystal composite structure includes M≥2 stacked two-dimensional perovskite single crystals; The crystal includes N≥2 layers of two-dimensional perovskite monolayer; the two-dimensional perovskite monolayer includes n layers of corner-sharing lead halide octahedra, n-1 layers of organic ligands A and 2 layers of organic ligands B, n≥1 , the chemical formula of the two-dimensional perovskite monolayer is B 2 A n-1 Pb n X 3n+1 , X is a halogen element, and the number of carbon atoms of the organic ligand B is greater than that of the organic ligand A; the same two-dimensional perovskite The 2D perovskite monolayer in the ore single crystal has the same n value, and the n value in the 2D perovskite single crystal far from the electron injection layer is larger than that of the 2D perovskite single crystal adjacent to the electron injection layer. It has the advantages of high injection efficiency, high environmental stability and high electro-optical conversion efficiency. |
