Title: Existence of a Size-Dependent Stokes Shift in CsPbBr 3 Perovskite Nanocrystals

Abstract

The existence of a size-dependent Stokes shift is observed in CsPbBr3 perovskite nanocrystals for the first time. Stokes shifts range from ~100 to 30 meV for particles with edge lengths between ~4 and 12 nm, respectively.
