摘要: This disclosure relates to an environmental-friendly and cost-efficient approach to synthesize CsPbBr3 powders in a large scale at room temperature with water. Using ultrasonication and centrifugation, CsPbBr3 nanocrystals can be obtained with green (˜522 nm) and blue (˜493 nm) emissions from the powders. The photoluminescence quantum yield of the blue-emitting nanocrystals is 80%, which is much larger than 61.4% of the CsPbBr3 nanocrystals made by an anti-solvent method. The green-emitting nanocrystals exhibit better stability than those made by the anti-solvent method over a period of 9 days. The method opens a new avenue to potentially produce inorganic and/or inorganic-organic hybrid halide perovskite nanocrystals without harmful organic solvents used in precursor solutions.

摘要: The present invention relates to a process for the synthesis of B-site doped ABX3 perovskite nanocrystals. The process comprises the steps of loading non-halide precursors of A, B, and dopant in three neck flasks along with long chain acid and olefin, purging of the reaction mixture under heating, and finally injection of alkylammonium chloride stock solution in the reaction mixture at a desired temperature. Introducing transition metal such as Mn and other rare earths, etc., as dopants in the perovskite nanocrystals to induce a new optical window.
