| titleOfInvention | A Ligand Regulation Method and Application of ABXnY3-n Perovskite Nanoparticles Based on Room Temperature Method |
| abstract | The invention belongs to the field of optoelectronic materials, and discloses a ligand regulation method and application of ABX n Y 3-n perovskite nanoparticles based on a room temperature method. Chain ligands, multiple precursors containing sodium ions and fatty acids are mixed, and quickly injected into the precursor containing B ions. After stirring, the precursor of alkyl ammonium halide is quickly added to it, and the perovskite nanometer can be obtained by continuing to stir. The crude liquid of the particles; the ligands on the surface can be obtained after washing treatment, and the ligands on the surface are mainly composed of long-chain ligand alkyl ammonium halide, long-chain ligand fatty acid, ultra-short-chain ligand and metal ligand sodium ions. ABX n Y 3 ‑n perovskite nanoparticles. In the present invention, by selecting ultra-short ligands and metal ligands Na + into the precursor, the surface long-chain ligands of the obtained perovskite nanoparticles are effectively reduced, the ultra-short-chain ligands are effectively increased, and both stability and The high-efficiency charge transport characteristics can greatly improve the device performance of light-emitting diodes based thereon. |
