| titleOfInvention | Manganese-doped two-dimensional lead-halogen perovskite material with high photoluminescence quantum yield and preparation thereof |
| abstract | The invention relates toA preparation method of a manganese-doped two-dimensional lead-halogen perovskite material with high photoluminescence quantum yield mainly comprises the following steps: (1) adding halogen acid into organic amine according to the molar ratio of 1:1, and stirring for 15min in ice bath; (2) putting the solution in an oven at 80 ℃ overnight until crystals are completely separated out; (3) washing the crystal with absolute ethyl alcohol, and drying in an oven at 80 ℃; (4) adding organic amine halide, lead halide and manganese halide in a certain proportion into a mortar, and uniformly grinding to obtain a final product. The general formula of the manganese-doped lead-halogen perovskite prepared by the invention satisfies (C) n H 2n+1 NH 3 ) 2 Pb 1‑x Mn x X 4 X is 0.001-0.95, has excellent optical performance, and has a central wavelength of 595-630nm, Mn 2+ The quantum yield of emission reaches 90%. Mn is realized by adjusting the chain length and the structure of organic amine salt and the type of halogen ion 2+ The emission wavelength can be controlled and adjusted, and the method is a simple and rapid preparation method of the manganese-doped two-dimensional lead halogen perovskite. |
