| titleOfInvention | Method for in-situ preparation of transition metal doped perovskite quantum dot film |
| abstract | The invention relates to a method for in-situ preparation of a transition metal doped perovskite quantum dot film, which comprises the steps of reacting cesium carbonate, lead oxide and acid in a polar solvent, mixing with a corresponding transition metal bromide solution, and adding a certain volume ratio of acid and alkali to enable the solution to be uniform and transparent. Finally, the prepared precursor solution is coated on a substrate such as glass, PET and the like, and is dried at a certain temperature to prepare the high-brightness CsPbBr 3 Green fluorescent film. The invention uses a polar solvent with low toxicity, low price and easy degradation and an acid-base ligand as a reaction system, uses a transition metal bromide as a bromine source and a doping agent, and adopts an in-situ one-pot preparation process to prepare the high-performance perovskite quantum dot film. The method is economic and environment-friendly, is simple to operate, and provides a new technology for the preparation of the perovskite quantum dots and the integration of photoelectric devices thereof. |
