Abstract

We demonstrate dynamical photo-physics of shape-engineered cube (6 facets), rhombic-dodecahedron (12 facets), and rhombicuboctahedron (26 facets) CsPbBr3 nanocrystals using ultrafast pump-probe spectroscopy. Results show remarkably contrasting carrier dynamics and Burstein-Moss effect for tuning optoelectronic properties.
