👉 Phosphorescent particles, often referred to as "light particles," are materials that absorb light energy and then re-emit it over time, typically in a longer wavelength (redder) spectrum. This process, known as phosphorescence, occurs when electrons in the particles become excited by external light or heat and then gradually release their energy as they return to their ground state. Unlike fluorescent materials, which emit light almost immediately after excitation and quickly fade, phosphorescent particles can retain their glow for extended periods, sometimes even hours or days, making them useful in applications like safety signage, watch faces, and decorative lighting. The "ph:light" aspect refers to the specific interaction or properties of these particles that allow them to store and slowly release light energy.
