Effect of Dimensionality on the Optical Absorption Properties of CsPbI${}_3$ Perovskite Nanocrystals

Albert Liu, Luiz G. Bonato, Francesco Sessa +7

The band-gaps of CsPbI${}_3$ perovskite nanocrystals are measured by absorption spectroscopy at cryogenic temperatures. Anomalous band-gap shifts are observed in CsPbI${}_3$ nanocubes…
