Nanoantenna sticker is a novel optical device in which periodic nanostructures are embedded in a polymer resin.
In this study, we utilized the Ag nanoantenna sticker, which show the quadrupolar resonance properties with high outcoupling efficiency than the common in-plane dipolar resonance, to combine with a lossless TiO2 nanoantenna designed for an absorption amplifyling layer. The remarkable improventment on the directional photoluminescence is demonstrated by stacking a two-layer nanoantennas.
