night glow pigment
Night glow pigment, also known as photoluminescent pigment, represents a groundbreaking advancement in luminescent technology. This innovative material absorbs and stores light energy from natural or artificial sources during exposure and releases it gradually in dark conditions, creating a lasting luminescent effect. The pigment consists of rare earth elements and strontium aluminate, which provides superior brightness and longer afterglow duration compared to traditional zinc sulfide-based materials. When exposed to light, the pigment's electrons become excited and move to a higher energy state, then gradually return to their ground state, releasing stored energy as visible light. This self-sustaining illumination can last for several hours, depending on the specific formulation and charging conditions. The pigment can be incorporated into various materials, including plastics, paints, inks, and textiles, making it versatile for numerous applications. Common uses include safety signage, emergency exit markers, decorative items, watch dials, and architectural elements. Its non-toxic and environmentally friendly nature, combined with its durability and weather resistance, makes it an ideal choice for both indoor and outdoor applications.
