Abstract
The present disclosure teaches an article of manufacture using an industrial (or commercial) manufacturing process. The article of manufacture comprises an infrared (IR) luminescent material that emits in the IR wavelength range (e.g., from approximately seven-hundred nanometers (~700nm) to approximately one millimeter (~1mm)) after being excited by incident wavelengths of between ~100nm and ~750nm (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 visible light.
