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: Article comprising particles in an organic polymer matrix comprising a cured thiol-alkene resin having a Tg>20° C., wherein the particles comprise a composite core and a continuous nonmetallic inorganic coating covering the composite core, wherein the composite core comprises a nonmetallic inorganic matrix, ligands, and quantum dots, wherein the nonmetallic inorganic matrix is present in the composite core in an amount of up to 40 volume percent, and wherein the coating has an average thickness up to 5 micrometers. Exemplary articles described herein can be made for use in display applications such as films, LED caps, LED coatings, LED lenses, and light guides. Exemplary articles described herein can be made for use in nondisplay applications such as security applications where quantum dot phosphors are used to provide fluorescence at selected or tailored wavelengths. In such uses, the organic polymer matrix could be a label or a coating on a label, or other articles such as a card or tag.

Abstract: Retroreflecting articles are described. In particular, retroreflecting articles including a quarter wave retarder and a retroreflecting layer are described. The retarder is rotationally invariant and the retroreflecting layer is non-depolarizing. Such articles may be useful for sensor-detectable signs, labels, and garments.
