The more the merrier: optimizing monomer concentration for supersaturation controlled synthesis of stable ultra-small CsPbBr₃ nanocrystals for blue emission

Abstract

a high-temperature (170 °C) colloidal approach by controlling the supersaturation reaction conditions. Our approach yielded stable nanocrystals with uniform size, shape, and excellent color purity, making them promising for blue light emitting diode (LED) applications.
