Title:
MANGANESE-DOPED ORGANIC PEROVSKITE CLUSTER MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/087449
Kind Code:
A1
Abstract:
A manganese-doped organic perovskite cluster material and a preparation method therefor. The preparation method comprises: dissolving AX and PbX2 in a solvent to obtain a first mixed solution, A being a monovalent organic cation, X being a halogen anion, and the molar weight of PbX2 being greater than that of AX; adding an organic carboxylic acid, an organic amine and a divalent manganese metal salt into the mixed solution to obtain a precursor solution, the molar ratio of the divalent manganese metal salt to PbX2 being 0.05-0.65:1; and mixing the precursor solution and an anti-solvent, and then performing solid-liquid separation to obtain a manganese-doped organic perovskite cluster material. The described preparation method has the characteristics of solution processing, rapid synthesis and low costs, and can obtain a doped perovskite cluster material having uniform size and excellent stability and optical properties.
