    Abstract: Techniques are described in which articles (e.g., security documents, traffic signage and personal protective equipment) are formed to include an infrared absorptive material. In some instances, the infrared absorptive material includes a reduced tungsten oxide, such as cesium tungsten oxide, calcium tungsten oxide, potassium tungsten oxide, or the like, and exposed to radiation such that one or more regions of the security document has a modified appearance, thereby providing a visual marking or information on the article. Example articles include at least one layer including a polymer and an infrared absorptive material including a reduced tungsten oxide. The layer includes a radiation-treated region that exhibits a first appearance under visible light and at least one non-radiation-treated region that exhibits a second, different appearance under visible light. The at least one radiation-treated region may be formed by exposing the at least one radiation-treated region to infrared light to change at least one property of the reduced tungsten oxide in the radiation-treated region compared to the reduced tungsten oxide in the non-radiation-treated region. The first appearance may be whiter than the second appearance.

    Abstract: An optical construction includes a lens film having outermost first and second major surfaces. The first major surface includes a plurality of microlenses. A multilayer mask having an average thickness of less than about 0.5 times an average focal length of the microlenses and an optical density of greater than about 2 is disposed on the second major surface. The multilayer mask includes polymeric first and second mask layers where each of the first and second mask layers has an optical density of greater than about 0.3. The multilayer mask defines a plurality of laser-ablated through openings therein that are aligned to the microlenses in a one-to-one correspondence. An optical transmittance of the optical construction as a function of the incident angle has a transmitted peak having a peak transmittance T1 and a corresponding full width at 20 percent of maximum W1, where T1/W1 ≥ 2.4%/degree.

    Abstract: Systems including one or both of a light emitter or a light receiver and an optical filter adjacent one or both of the light emitter or the light receive are described. The optical filter includes a wavelength selective scattering layer that scatters near-infrared light less than visible light. The wavelength selective scattering layer includes a plurality of particles. The plurality of particles have an imaginary refractive index less than 10.

    Abstract: Composite particles comprising quantum dot light emitters, a nonvolatile liquid ligand system, and hydrolyzed organometallic metal oxide precursor, wherein the quantum dot light emitters and the nonvolatile liquid ligand system are collectively present in the composite particles in an amount of at least 30 weight percent. Composite particles described herein are useful, for example, in films (e.g., remote phosphor diffuser films). Remote phosphor diffuser films are useful, for example, in LCD displays.
