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.
Claims3
An article of manufacture, wherein the article of manufacture is manufactured using an industrial or commercial process, wherein the article of manufacture resists degradation in temperatures that range from approximately negative forty degrees Fahrenheit (−40° F.) to approximately one-hundred-and-sixty-five degrees Fahrenheit (165° F.), wherein the article of manufacture comprises:
- a substrate that does not exhibit infrared (IR) phosphorescence, wherein the substrate is a first injection-molded polyvinyl chloride (PVC) material that is formed in a multi-component injection-molding process, wherein the first PVC material is flexible;
- and
- an IR phosphorescent material that is formed atop the substrate in the multi-component injection-molding process, wherein the IR phosphorescent material is a second injection-molded PVC material, wherein the second PVC material is flexible, wherein the IR phosphorescent material phosphoresces for longer than four (4) hours after being exposed to visible light, wherein the IR phosphorescent material is detectable from a distance of greater than approximately one kilometer (˜1 km), wherein the IR phosphorescent material comprises an emission wavelength, wherein the emission wavelength is one selected from the group consisting of:
- a wavelength range that is between approximately 700 nanometers (˜700 nm) to approximately one millimeter (˜1 mm);
- a wavelength range that is between approximately nine-hundred-and-twenty (˜920 nm) to approximately 1550 nanometers (˜1550 nm);
- a wavelength range that is near infrared (NIR);
- a wavelength range that is short-wave infrared (SWIR);
- a wavelength that is centered at approximately seven-hundred-and-sixty nanometers (˜760 nm);
- a wavelength that is centered at approximately nine-hundred-and-twenty nanometers (˜920 nm);
- a wavelength that is centered at approximately nine hundred nanometers (˜900 nm);
- and
- a wavelength that is centered at approximately one-thousand-five-hundred-and-fifty nanometers (˜1550 nm).
