Abstract: An optically diffusive film includes a structured first major surface with a plurality of substantially parallel, substantially planar first surfaces arranged across the first major surface at a plurality of different first height levels. A height difference between any two of the first surfaces is S times Hmin, where S is a number within 15% of an integer and Hmin is a height difference between lowest and next-lowest first surfaces. For a substantially collimated incident light and for a first wavelength in a human-visible wavelength range, the optically diffusive film has an optical haze, Hv, and an optical clarity, Cv, and for a second wavelength in an infrared wavelength range, the optically diffusive film has an optical haze, Hi, and an optical clarity, Ci, such that the ratio Hv/Hi is greater than or equal to 1.5 and the ratio Ci/Cv is greater than or equal to 1.5.

Abstract: The present disclosure provides an article including a layer having a nanostructured first surface including nanofeatures and an opposing second surface, and an organic layer including a major surface attached to a portion of the nanofeatures. The nanostructured first surface includes protruding features that are formed of a single composition and/or recessed features. The nanofeatures and the major surface of the second layer together define at least one void. The present disclosure also provides a method of making the article including contacting nanofeatures of a layer having a nanostructured surface with a major surface of an organic layer and reacting at least one material to secure the two layers together. In addition, the present disclosure provides an optical information display and an OLED device including the article. The nanostructured surface of the article is protected from damage and contamination by the organic layer.

Abstract: Nanostructured articles, materials for the nanostructured articles, and intermediate articles for use in making the nanostructured articles. The nanostructured articles can be formed on a flexible film and are useful for optical metasurface applications and possibly other applications. The articles can include nanoreplicated layers or pattern transfer layers of engineered nanostructures.

Abstract: A nanostructured article having a first layer with a nanostructured surface is described. The nanostructured surface includes a plurality of pillars extending from a base surface of the first layer. The pillars have an average height greater than an average lateral dimension of the pillars. An average center-to-center spacing between pillars is no more than 2000 nm. The average lateral dimension is no less than 50 nm. Each pillar in the plurality of pillars has at least a lower portion and an upper portion where the lower portion is between the upper portion and the base surface, and the upper and lower portions have differing compositions. The nanostructured article includes a second layer disposed over the plurality of pillars and extending continuously to the base surface.

Abstract: The present disclosure describes nano-structured light extraction color filter laminates, and articles and methods of using nanostructured light extraction color filter laminates for the fabrication of an OLED including a nanostructure, using lamination techniques. Nanostructured OLED devices can exhibit enhanced light extraction efficiency. The methods involve transfer and/or replication of a film, layer, or coating in order to form a nanostructured surface that is in optical contact with the emitting surface of an OLED in, for example, a top emitting or a bottom emitting active matrix OLED (TE-AMOLED or BE-AMOLED) device. The articles having enhanced light extraction efficiency can be of particular use in color-by-white (CBW) OLED displays, which use white-light spectrum OLEDs with a color filter array.
