Infrared (IR) luminescent material

An article of manufacture comprising:

• a flexible injection-molded polyvinyl chloride (PVC) substrate that is manufactured using an industrial or commercial injection-molding process, the substrate resisting degradation in temperatures ranging from approximately negative forty degrees Fahrenheit (−40° F.) to approximately one-hundred-and-sixty-five degrees Fahrenheit (165° F.);
• and
• infrared (IR) phosphorescent particles that phosphoresce for more than four (4) hours upon being exposed to approximately fifteen (˜15) minutes of visible light, the IR phosphorescent particles forming a pattern on the substrate, the pattern being formed using an industrial or commercial manufacturing process, the IR phosphorescent particles having a particle size that ranges from approximately one-and-a-half nanometers (˜1.5 nm) to approximately six hundred micrometers (˜600 μm), the IR phosphorescent particles resisting degradation in temperatures ranging from approximately −40° F. to approximately 165° F. the IR phosphorescent particles comprising a combination of Zinc (Zn), Antimony (Sb), Gallium (Ga), Tellurium (Te), Oxygen (O), Nitrogen (N), Chromium (Cr), and Neodymium (Nd).
