Separation of mono-dispersed CH3NH3PbBr3Perovskite Quantum dots via dissolution of nanocrystals

Separation of mono-dispersed CH3NH3PbBr3 perovskite quantum dots (PeQDs) using the Ostwald ripening process during aging of the perovskite nanocrystals (PeNCs) in a colloidal solution is proposed for color-tunable PeQD synthesis. Monodispersed PeNCs with size ranging from 5 to 17 nm with a spherical...

Zusammenfassung:	Separation of mono-dispersed CH3NH3PbBr3 perovskite quantum dots (PeQDs) using the Ostwald ripening process during aging of the perovskite nanocrystals (PeNCs) in a colloidal solution is proposed for color-tunable PeQD synthesis. Monodispersed PeNCs with size ranging from 5 to 17 nm with a spherical or square shape have been successfully prepared. Photo-luminescence spectroscopy revealed the quantum confinement effect on the spherical small QDs.
