Abstract: Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape).

Abstract: A cooperative vehicle-highway communication system allows vehicles and pedestrians to determine their location by sensing selected coatings on roadways, sidewalks, and other paved surfaces in both indoor and outdoor environments. The systems recognize intelligent materials under sensors to determine geo-location. The intelligent materials are incorporated into paints on the roadway surface to mark key locations. Additionally, vehicles recognize highway paint/markings and signs with intelligent paint that provide specialized message content to support driver information and control applications. The intelligent paint materials include a coating that absorbs light while converting the absorbed light to electromagnetic energy. This electromagnetic energy is read by sensors to recognize the materials.

Abstract: New methods and assays for multiplexed detection of analytes using phosphors that are uniform in morphology, size, and composition based on their unique optical lifetime signatures are described herein. The described assays and methods can be used for imaging or detection of multiple unique chemical or biological markers simultaneously in a single assay readout.

Abstract: There is disclosed a topical composition comprising at least one organic and/or inorganic phosphor in a physiologically acceptable medium, wherein the phosphor(s) is present in an amount effective to convert electromagnetic radiation of an initial frequency to a different frequency. In one embodiment, the phosphors convert the initial radiation frequency, such as infrared or visible light, to a higher frequency, such as ultraviolet (UV) radiation. In another embodiment, the phosphors convert the initial radiation from a higher frequency, such as UV radiation, to a lower frequency, such as infrared or visible light. Methods of treating keratinous material, such as the skin, hair, or lips, using the disclosed compositions are also disclosed.
