| titleOfInvention | Blue perovskite film and blue perovskite light-emitting diode |
| abstract | The invention relates to a preparation method of a blue light perovskite film, which comprises the following steps: dissolving PEABr, NPABr 2 , CsBr and PbBr 2 in an organic solvent to obtain a perovskite precursor solution; in the perovskite precursor solution, PbBr The molar concentration of 2 is 0.05-0.2mM/mL, and the molar ratio of PEABr, NPABr 2 , CsBr and PbBr 2 is 0.4-0.9:0.3-0.6:0.9-1.2:1; the perovskite precursor solution is coated on the lining The bottom surface was annealed at 60-80 °C, and a blue-light perovskite film was obtained after annealing. The invention also discloses a blue light perovskite light emitting diode based on the blue light perovskite film prepared by the above method, which comprises a transparent conductive substrate, a hole transport layer, a blue light perovskite film, an electron transport layer, Electron injection layer and metal cathode electrode. |
