CH₃NH₃PbBr₃ perovskite nanocrystals (PeNCs) are applied for various optical devices like light emitting diodes. Although many bottom-up syntheses have been reported, we successfully synthesized PeNCs using ultrasound-assisted milling which could be expected for scalable synthesis. We report on milling conditions affected optical properties in detail.
