By coupling gap plasmons in aluminium plasmonic nanoparticle arrays with an ultra-thin layer of electrochromic WO3, we demonstrate how one can electrochemically tune the structural color of a completely solid-state device! Our results have recently been published in Nano Letters.

In our recent paper in Nature Communications we demonstrate a transparent photodetector with color and polarisation detection, by using a new type of optical resonance in silicon nanowire arrays!
