Abstract

See full text

A multilayer thin film that reflects an omnidirectional structural color includes a multilayer stack comprising having: a reflector layer; a first dielectric layer extending over the reflector layer; an absorbing layer extending over the first dielectric layer; and a second dielectric layer extending over the absorbing layer. The multilayer thin film reflects a single narrow band of visible light when exposed to broadband electromagnetic radiation, and the single narrow band of visible light has: a visible full width at half maximum (FWHM) width of less than 200 nm; a color shift of the reflected single narrow band of visible light is less than 50 nm when the multilayer stack is exposed to broadband electromagnetic radiation and viewed from angles between 0 and 45 degrees relative to a direction normal to an outer surface of the multilayer thin film.
