Abstract
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.
