Abstract
A multilayer stack displaying a red omnidirectional structural color. The multilayer stack includes a reflector layer, a dielectric layer extending across the reflector layer, and an absorbing layer extending across the dielectric layer. The dielectric layer reflects more than 70% of incident white light that has a wavelength greater than 580 nanometers (nm). In addition, the absorbing layer absorbs more than 70% of the incident white light with a wavelength less than 580 nm. In combination, the reflector layer, dielectric layer, and absorbing layer form an omnidirectional reflector that reflects a narrow band of electromagnetic radiation with a center wavelength between 580-680 nm, has a width of less than 200 nm wide and a color shift of less than 100 nm when the reflector is viewed from angles between 0 and 45 degrees.
