Periodic arrays of metallic nanoparticles act as metasurfaces to control light at the interface. Although combination of a variety of functional materials with metasurfaces should open a rich scientific research field, the application degree of freedom is limited severely by the fabrication process. We developed a metasurface sticker that can be stuck on any surfaces and gives a control over in- and out coupling of light. We demonstrate a photoluminescence outcoupling by placing a sticker on the luminescent layers: the emission pattern is modulated both spatially and spectrally in a way defined by the metasurface sticker. The sticker is useful for enhancing optical response from many different surfaces including those which are incompatible with the nanofabrication processes and should help the integration of metasurfaces into functional devices.
