Abstract
AbstractA top‐down method is demonstrated for the fabrication of CH3NH3PbBr3 and CH3NH3PbI3 perovskite nanocrystals, employing a mixture of ligands oleic acid and oleylamine as coordinating solvents. This approach avoids the use of any polar solvents, skips multiple reaction steps by employing a simple ultrasonic treatment of the perovskite precursors, and yields rather monodisperse blue‐, green‐, and red‐emitting methylammonium lead halide nanocrystals with a high photoluminescence quantum yield (up to 72 % for the green‐emitting nanocrystals) and remarkably improved stability. After discussing all relevant reaction parameters, the green‐emitting CH3NH3PbBr3 nanocrystals are employed as a component of down‐conversion white‐light‐emitting devices.
