Abstract

We fabricated dielectric nanoantenna stickers comprising a periodic array of TiO₂ nanoparticles embedded inside the polydimethylsiloxane (PDMS). For the fabrication, we first used a nanoimprint to make a square lattice of TiO₂ nanoparticles on the SiO₂ glass substrate, and then covered it with a PDMS film. Finally, the nanoantenna was transferred from the substrate to the PDMS by dissolving the sacrifice layer between the nanoantenna and the substrate. We found that poly(sodium-4-styrene sulfonate) was suitable as the water-soluble sacrifice layer for the transfer of TiO₂ nanoantenna. As a demonstration, we placed the TiO₂ nanoantenna sticker on top of the light-emitting layer. The emission from the emitter layer was enhanced directionally following the dispersion of lattice resonances excited in the sticker.
