摘要： A hybrid solar window comprises: at least one glazing; a wavelength-selective solar mirror positioned to reflect IR toward an IR absorbing element. The IR absorbing elements comprises a conduit having a respective fluid inlet and fluid outlet, and an IR absorbing compound, wherein the IR absorbing compound is in thermal communication with the conduit. The wavelength-selective solar mirror has an average visible light transmittance of at least 50 percent and an average IR reflectance of at least 50 percent over the wavelength range of 850 to 1150 nanometers, inclusive. The IR absorbing element is configured to transfer thermal energy to a heat transfer fluid circulating through the conduit, wherein the IR absorbing element has an average visible light transmittance of at least 30 percent, and wherein each IR absorbing element has an average IR absorptance of at least 50 percent over the wavelength range 850 to 1150 nanometers, inclusive. Certain IR absorbing elements are also disclosed.

摘要： 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.
