Researchers have built a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using ...

Now researchers in Japan have reported the world’s first continuous-wave UV-B semiconductor laser diode operating at room temperature on a low-cost sapphire substrate. This breakthrough by researchers ...

Ultraviolet light has always sat at the edge of human perception, powerful yet invisible, more associated with sterilizing ...

Ultraviolet light emitting diodes (UV-LEDs) have rapidly evolved as a promising alternative to conventional mercury-based UV lamps in water disinfection systems. Their compact size, reduced energy ...

The world’s astronomers now have access to amazing details about the invisible ultraviolet light from the Sun, thanks to a new ‘spectral atlas’ prepared with the SUMER instrument on the SOHO ...

A bus being treated with ultraviolet light in Shanghai, China. Although types of UV light are already in use to decontaminate vehicles and indoor spaces, the wavelengths used are dangerous to people.

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...
