△ [20a-A204-10] Size control of CH3NH3PbBr3 perovskite quantum dots via Ostwald ripening
Keywords:perovskite, reprecipitation, quantum Dots
CH3NH3PbBr3 perovskite quantum dots (PeQDs) are expected to be applied to versatile optical devices such as Solar cells, LED, and Lasers. We successfully synthesize perovskite quantum (PeQDs) by ligand-assisted reprecipitation and obtained PeQDs are precisely size-controlled from 16.7 nm to 5.3 nm via Ostwald ripening. We will report on reprecipitation conditions and optical characteristics from size-controlled PeQDs in detail.
