Fluorescents: Minerals that Glow in the Dark

Fluorescence refers to the visible light materials give off when exposed to invisible ultraviolet light. Most minerals do not fluoresce. But a few contain atoms in which electrons become boosted to a higher energy level by ultraviolet light. When these electrons fall back to their original state, they give off energy in the form of visible light.
