    摘要： In one embodiment, a semi-transparent reflector may include a multilayered photonic structure. The multilayered photonic structure includes a plurality of coating layers of high index dielectric material and a plurality of coating layers of low index dielectric material. The plurality of coating layers of high index dielectric material and the plurality of coating layers of low index dielectric material of the multilayered photonic structure are arranged in an [LH . . . (LH)N . . . L] structure. L is one of the plurality of coating layers of low index dielectric material. H is one of the plurality of coating layers of high index dielectric material. N is a positive integer. The multilayered photonic structure has substantially constant reflectance values for wavelengths of electromagnetic radiation in a visible spectrum over a range of angles of incidence of the electromagnetic radiation.

    摘要： The present invention provides an omnidirectional ultraviolet (UV)-infrared (IR) reflector. The omnidirectional UV-IR reflector includes a multilayer stack having at least three layers, the at least three layers having at least one first index of refraction material A1 and at least one second index of refraction layer B1. The at least one first index of refraction material layer and the at least one second index of refraction material layer can be alternately stacked on top of each other to provide the at least three layers. In addition, the at least one first index of refraction material layer and the at least one second index of refraction material layer each have a predefined thickness of dA1 and dB1, respectively, with the thickness dA1 not being generally equal to the dB1 thickness such that the multilayer stack has a non-periodic layered structure.

    摘要： A multi-layer photonic structure may include alternating layers of high index material and low index material having a form [H(LH)N] where, H is a layer of high index material, L is a layer of low index material and N is a number of pairs of layers of high index material and layers of low index material. N may be an integer ≧1. The low index dielectric material may have an index of refraction nL from about 1.3 to about 2.5. The high index dielectric material may have an index of refraction nH from about 1.8 to about 3.5, wherein nH>nL and the multi-layer photonic structure comprises a reflectivity band of greater than about 200 nm for light having angles of incidence from about 0 degrees to about 80 degrees relative to the multi-layer photonic structure. The multi-layer photonic structure may be incorporated into a paint or coating system thereby forming an omni-directional reflective paint or coating.

    摘要： Disclosed is a multilayer structure wherein a first layer of a first material having an outer surface and a refracted index between 2 and 4 extends across an outer surface of a second layer having a refractive index between 1 and 3. The multilayer stack has a reflective band of less than 200 nanometers when viewed from angles between 0° and 80° and can be used to reflect a narrow range of electromagnetic radiation in the ultraviolet, visible and infrared spectrum ranges. In some instances, the reflection band of the multilayer structure is less than 100 nanometers. In addition, the multilayer structure can have a quantity defined as a range to mid-range ratio percentage of less than 2%.
