Phosphorescence is a phenomenon where certain materials glow in the dark after being exposed to light, because they absorb and slowly release light energy over time. This property is useful for creating glow-in-the-dark products like safety signs and decorative items, and can be enhanced by adding special elements like europium to materials such as strontium silicate-aluminate oxide.
