Elucidation of Ostwald Ripening Process for Perovskite Nanocrystals

Abstract

Perovskite nanocrystals (PeNCs) have superior optical properties like narrow half width and a high quantum yield and are expected as a photonic source for a wide color gamut display. However, precise controlling of the PeNC sizes which is capable to demonstrate the PL peaks in wide range has not been developed. From the above background, we have been proposing a down-sizing protocol preparing for the PeNCs using Ostwald ripening, and we elucidate the PL behavior from the down-sized PeNCs in this report.
