| titleOfInvention | Inverse temperature solution growth method of all-inorganic perovskite single crystal |
| abstract | The invention discloses an inverse temperature solution growth method of an all-inorganic perovskite single crystal, which is used for solving the technical problem of poor practicability of the existing growth method of the all-inorganic perovskite single crystal. The technical proposal is thatFirstly, mixing cesium bromide and lead bromide serving as raw materials in an organic solvent dimethyl sulfoxide for dissolving and stirring, filtering, and adding a mixed solution of cyclohexanol and dimethylformamide to obtain a precursor solution; secondly, preserving the heat of the precursor solution for a certain time at a certain temperature, and filtering the solution with precipitated crystals; finally, the filtrate is placed in a water tank for heating and temperature rise, and CsPbBr with large size and high crystallization quality grows 3 And (4) crystals. The CsPbBr prepared by the method of the invention 3 The XRD pattern of the powder is consistent with that of a standard structure card, and the CsPbBr is proved 3 The powder was pure phase and obtained was × long, × wide, (4-7) × (3-5) × (2-3) mm 3 CsPbBr of 3 The single crystal has good practicability. |
