Organometallic Perovskites: Organometallic Perovskite Metasurfaces (Adv. Mater. 9/2017)

Abstract

Organometallic perovskites, solution-processable materials with outstanding optoelectronic properties and high refractive index, provide a unique platform for alldielectric metamaterials operating at visible frequencies. In article number 1604268, Cesare Soci and co-workers realize perovskite metasurfaces with structural coloring tunable across visible frequencies, which also yields a three-fold increase of luminescence emission in comparison with unstructured perovskite films.
