A simple spray converts lead contamination into glowing green perovskites, visible under ultraviolet light. Chemists were trying to make semiconductor materials called perovskites when they found that lead in the environment triggers the same material to form. The reaction works with a variety of lead compounds and materials, providing a fast and easy way to see lead in the environment.

Narrator: This shining crack is not a rift in space-time. It’s hazardous lead contamination.
Chemists were trying to make semiconductor materials called perovskites when they found that lead in the environment triggers the same material to form. They made a spray that converts the lead into perovskites that glow under UV light. The reaction works with a variety of lead compounds and materials, providing a fast and easy way to see lead in the environment.
