What stuff is phosepherescent?

Phosphorescent materials absorb energy and then re-emit it slowly over time, creating a glow in the dark. Common examples include certain types of glow-in-the-dark paints, toys, and stickers, which often contain zinc sulfide or strontium aluminate. Some minerals, like willemite, also exhibit phosphorescence. Additionally, certain organisms, such as some jellyfish and fungi, can display phosphorescent properties.
