Perovskite nanocrystals (PeNCs) with excellent optical properties are expected to be used as a light source to improve color gamut of displays. In this work, we attempted to synthesize PeNCs by the “ultrasound-assisted beads milling” which is novel synthesis method with collision of beads, and ultrasonic cavitation. Preparation of PeNCs with uniform size can be achieved by this synthesis method.
