A display that includes an image producing system and a light filtering layer in the blue range, the light filtering layer having a limited impact on the gamut of the display. The image producing system has a gamut G.sub.0 defined in a color space The light filtering layer includes semi-conductive nanoparticles, and the absorbance through the light filtering layer is greater than 0.25 for each light wavelength ranging from 350 nm to λ.sub.cut, λ.sub.cut being in the range from 420 nm to 450 nm. The gamut G.sub.1 of the image producing system with the filtering layer has an area greater than 90% of the area of gamut G.sub.0 in the color space.

A reflective paint's liquid mixture includes 42.4-71.3 weight percent of a liquid solvent, 14.4-28.3 weight percent of a binder fully dissolved in the liquid solvent, and 13.8-29.3 weight percent of light scattering particles that are insoluble in the liquid solvent and are of a size ranging from 100 nanometers to 200 nanometers. The binder is selected from potassium bromide, sodium chloride, potassium chloride, sodium bromide, cesium chloride, and rubidium chloride. The light scattering particles are selected from hafnium oxide and yttrium oxide. The reflective paint is particularly useful as a surface coating for a variety of structures that must support cryogenic temperatures. It can be used in any application to act as a broadband reflector of the Sun's radiation in the wavelength band from approximately 0.21 microns to 9 microns and beyond.

This invention is a commercially manufactured article of manufacture (such as a shoulder patch) comprising an infrared (IR) phosphorescent material that emits in the IR wavelength range (e.g., from approximately seven-hundred nanometers (˜700 nm) to approximately one millimeter (˜1 mm)) after being excited by incident wavelengths of between ˜100 nm and ˜750 nm (or visible light). In other words, once the material has been exposed to visible light, the material will continue to emit in the IR wavelength range for a period of time, even when the material is no longer exposed to the visible light.
