Abstract: An optical metasurface film includes a flexible polymeric film having a first major surface, a patterned polymer layer having a first surface proximate to the first major surface of the flexible polymeric film and having a second nanostructured surface opposite the first surface, and a refractive index contrast layer including a refractive index contrast material adjacent to the nanostructured surface of the patterned polymer layer forming a nanostructured bilayer with a nano structured interface. The nanostructured bilayer comprising a plurality of nanostructures disposed on the flexible polymeric film. The nanostructured bilayer imparts a light phase shift that varies as a function of position of the nano structured bilayer on the flexible polymeric film. The light phase shift of the nanostructured bilayer defines a predetermined operative phase profile of the optical metasurface film. A light reflecting layer is in optical communication with the nano structured bilayer.

Abstract: Various embodiments disclosed relate to a resin including nanoparticles including surface-bonded hydrophobically-modifying alkyl groups. The present invention provides a resin component that includes a curable resin. The resin component also includes nanoparticles dispersed in the resin. The nanoparticles each independently include surface-bonded hydrophobically-modifying (C1-C50)hydrocarbyl groups. At least one of the (C1-C50)hydrocarbyl groups is a (C1-C50)alkyl group and at least one of the surface-bonded hydrophobically-modifying (C1-C50)hydrocarbyl groups is a (C6-C50)aryl group.

Abstract: An emissive article includes an OLED having a light emission surface, a circular polarizer, and a light extraction film optically between the OLED and the circular polarizer and being optically coupled to the light emission surface. The light extraction film includes a two-dimensional structured layer of extraction elements having a first index of refraction and a pitch in a range from 400 to 800 nm and a backfill layer including a material having a second index of refraction different from the first index of refraction.
