Abstract: Disclosed is a method for preparing a perovskite nanoparticle using a fluidic channel including a first step of forming a fluidic channel including a first outer tube, a second outer tube, and a storage tube capable of introducing flows of fluids, a second step of inducing formation of the perovskite nanoparticles by continuously preparing a mixed fluid with a laminar flow based on a flow rate by introducing a flow of a base fluid into the first outer tube, and introducing a flow of a dispersion fluid in the same direction as the flow of the base fluid into the second outer tube, and a third step of separating the perovskite nanoparticles from the mixed fluid stored in the storage tube.

Abstract: A method of producing perovskite nanocrystalline particles using a fluid mold includes a first operation for preparing a mixed solution including a first precursor compound, a second precursor compound, and a first solvent. A second operation for preparing a precursor solution by adding an organic ligand to the prepared mixed solution, a third operation for performing crystallization treatment after adding the prepared precursor solution to a reactor containing a fluid mold, and a fourth operation for separating the perovskite nanocrystalline particles from the crystallized solution through a centrifugal separator.
