Optical Properties of Thin Films of Tin Iodide Perovskite Nanostructures

Advanced Optical Materials, EarlyView.
A comprehensive spectroscopic study of thin films of 3D CsSnI3 nanocrystals (NCs) that coexist with residual 2D Ruddlesden‐Popper nanosheets (NSs) has been performed. Polymer encapsulation enables solid‐state stabilization of the tin iodide perovskite nanostructures, while insight into the energetics and dynamics of the NC and NS excitons is provided ...
