title: Control of Emission Color of High Quantum Yield CH3NH3PbBr3Perovskite Quantum Dots by Precipitation Temperature.
abstract: Emission color controlled, high quantum yield CH3NH3PbBr3perovskite quantum dotsare obtained by changing the temperature of a bad solvent during synthesis. The products for temperatures between 0 and 60 °C have good spectral purity with narrow emission line widths of 28-36 nm, high absolute emission quantum yields of 74% to 93%, and short radiative lifetimes of 13-27 ns.
