Abstract
Here, we developed humidity-responsive full color nano-pixels with 700nm resolution using 3D nanoimprinted polyvinyl alcohol (PVA) and disordered silver nanoparticles (NPs). The nano-pixels are designed as Fabry-Pérot structure which is composed of an aluminum mirror substrate, humidity-responsive PVA spacer, and disordered silver nanoparticles as top metal layer. The proposed structure has three main merits as follows. It has 1) high resolution thanks to 3D nanoimprinted PVA technique, and 2) millisecond-response time (441ms), 3) vivid color generation thanks to disordered silver NPs which enhance the penetration speed of water molecules into the PVA layer and have highly absorbing dielectric optical property.
