Fluorescent minerals
Fluorescent minerals emit visible light when exposed to ultraviolet radiation. The effect comes from trace activator ions in the crystal lattice, manganese, uranium, rare earths, and the response often differs between short-wave and long-wave UV. Many are unremarkable in daylight and dazzling under a UV lamp.
