Structural Color Images
In article number 2102451, Magnus P. Jonsson and co‐workers demonstrate a new approach to produce dynamic structural colors with UV‐patterned conducting polymers. The UV patterning controls the film thickness and polymer permittivity, and enables production of multicolor images with a single exposure step. Combined with the electrochemical tunability of the conducting polymer,...
Precise manipulation of light–matter interactions has enabled a wide variety of approaches to create bright and vivid structural colors. Techniques utilizing photonic crystals, Fabry–Pérot cavities, plasmonics, or high‐refractive‐index dielectric metasurfaces have been studied for applications ranging from optical coatings to reflective displays. However, complicated fabrication procedures for sub‐wavelength...
