Key Points

This research aims to investigate how halide ions exchange and mix in fresh and aged mixtures of CsPbI3 and CsPbBr3 nanocrystals.
Analyzed fresh and aged CsPbI3-CsPbBr3 nanocrystals
Studied mixing behavior of halide ions
Measured quantum yield and absorption characteristics
Both fresh and aged mixtures showed high quantum yield
Mixing behavior differed between fresh and aged samples
Results indicate potential stability issues in aged nanocrystals

Implication

Ultrahigh quantum yield and tunable bandgap revealed ion exchange dynamics in perovskite nanocrystals, suggesting stability implications.

Abstract

Ultrahigh quantum yield, bandgap tunability, and high absorption coefficient makes CsPbI 3-x Br x perovskites ideal candidates for various optoelectronic applications. Post synthesis mixing of CsPbI 3 and CsPbBr 3 nanocrystals (NCs) is an...
