  • Patent number: 10048415
    Abstract: A non-dichroic omnidirectional structural color multilayer structure. The non-dichroic omnidirectional structural color multilayer structure has an absorbing layer, a first layer extending across the absorbing layer, and a second layer extending across the first layer. The multilayer structure can reflect a narrow band of electromagnetic radiation that has a width of less than 500 nanometers and a center wavelength shift of less than 200 nanometers when the multilayer structure is viewed from angles between 0 and 45 degrees. In addition, the absorbing layer can block electromagnetic radiation reflected off of a surface that is proximate to the multilayer structure and thereby afford for a “pure” color that is not contaminated by reflected light from surrounding surfaces.
