Organometallic perovskite metasurfaces
Dielectric metamaterials are widely explored as low-loss alternative to their plasmonic counterparts, which suffer from substantial Ohmic losses at optical frequencies. Here we demonstrate that organometallic perovskites, emerging solution-processable materials with outstanding optoelectronic properties and high index of refraction, provide a platform for all-dielectric metamaterials operating at visible frequencies. We show organolead halide perovskite metasurfaces with structural colouring tunable across the visible spectrum through sub-wavelength structuring. Moreover, we demonstrate that nanostructured perovskite films exhibit enhanced photoluminescence. We observed a three-fold increase of the luminescence yield and comparable reduction of luminescence decay time in comparison with unstructured perovskites films. We argue that nanostructured, solution processable organometallic perovskites metamaterials prepared by nanoimprint could be a low cost solution for photovoltaic energy conversion, large-area light-emitting devices, and artificial colouring for display applications.

Abstract

Dielectric metamaterials are widely explored as low-loss alternative to their plasmonic counterparts, which suffer from substantial Ohmic losses at optical frequencies. Here we demonstrate that organometallic perovskites, emerging solution-processable materials with outstanding optoelectronic properties and high index of refraction, provide a platform for all-dielectric metamaterials operating at visible frequencies. We show organolead halide perovskite metasurfaces with structural colouring tunable across the visible spectrum through sub-wavelength structuring. Moreover, we demonstrate that nanostructured perovskite films exhibit enhanced photoluminescence. We observed a three-fold increase of the luminescence yield and comparable reduction of luminescence decay time in comparison with unstructured perovskites films. We argue that nanostructured, solution processable organometallic perovskites metamaterials prepared by nanoimprint could be a low cost solution for photovoltaic energy conversion, large-area light-emitting devices, and artificial colouring for display applications.
