Abstract

See full text

An omnidirectional multilayer thin film is provided. The multilayer thin film includes a multilayer stack having a first layer of a first material and a second layer of a second material, the second layer extending across the first layer. The multilayer stack reflects a narrow band of electromagnetic radiation having a full width at half maximum (FWHM) of less than 300 nanometers (nm) and a color/hue shift of less than 30 degrees when the multilayer stack is exposed to broadband electromagnetic radiation and viewed from angles between 0 and 45 degrees. In some instances, the multilayer stack has a total thickness of less than 2 microns (μm). Preferably, the multilayer thin film has a total thickness of less than 1.5 μm and more preferably less than 1.0 μm.
