UV light reveals a version of the world humans were never meant to see. Everyday objects, clothing, skin, and even surfaces you think are clean suddenly look completely different under ultraviolet.

An international research team has achieved record perovskite solar module stability under light, heat, and UV stress with a chemistry-driven passivation technology that is industry-compatible.

A programmable semiconductor changes its electronic properties under UV light and reverts under a different wavelength, enabling optical writing and reading for potential computing applications.

... this only occurs in specific, somewhat rare conditions. Otherwise, clouds generally tend to dampen UV rays. In short, while studies have found that clouds can ...

UV-C light is a type of ultraviolet light with shorter wavelength and more energy than UV light of type A and B. Photonic components operating in the UV-C range can unlock new opportunities across ...

Six species of North American bats—big brown bats (pictured), eastern red bats, Seminole bats, southeastern myotis, gray bats and Brazilian free-tailed bats—glow green under ultraviolet light, new ...

A recent University of Georgia study found that bats glow a greenish tone under ultraviolet light. Scientists have not yet determined the reason for this glowing characteristic in bats. The study ...
