Nanostructures Take Color, Reflection from Thin Films

Caption

This image shows how moth-inspired nanostructures stop thin-film interference by blocking reflected light. The images on the far right show a slide with no thin film. The images in the middle show the slide coated with thin films. Note how thin-film interference results in a variety of colors. The images on the left are of the slide coated with thin films containing the nanostructures. Note the absence of color, and significantly less reflected light.
