Description
Summary:Organometallic perovskites, solution‐processable materials with outstanding optoelectronic properties and high index of refraction, provide a platform for all‐dielectric metamaterials operating at visible frequencies. Perovskite metasurfaces with structural coloring tunable across visible frequencies are realized through subwavelength structuring. Moreover, a threefold increase of the luminescence yield and comparable reduction of luminescence decay time are observed.
