Night Glow

Night glow is a natural phenomenon where certain materials emit visible light in the dark after being exposed to sunlight or artificial light. This glow occurs because these materials, called phosphors, absorb energy during the day and slowly release it as light during the night. Common examples include glow-in-the-dark stars, watch dials, and some minerals. The process involves storing energy and gradually releasing it, creating a gentle, sustained illumination without additional power, making it useful for safety signs, decorative items, and timepieces.
