Abstract

We report the ultrasound-induced synthesis of APbX3 perovskite nanocrystals with a wide range of compositions, where A = CH3NH3, Cs, or HNCHNH3 (formamidinium), and X = Cl, Br, or I. Ultrasonic irradiation accelerates dissolution of the precursors (AX and PbX2) in toluene, and the dissolution rate determines the growth rate of the nanocrystals. We fabricated high-sensitivity photodetectors by homogenously spin coating the uniform size nanocrystals on large-area silicon oxide substrates.
