Ultraviolet light occurs between the visible and x‐ray spectrums. The Ultraviolet wavelength range is specified as 10 nm to 400 nm; however, many optoelectronic companies also consider wavelengths as ...

For the first time, scientists have used ultraviolet (UV) light, a low-cost and readily available energy source, to successfully synthesize more sustainable and recyclable polymer materials. Led by ...

Even though we're warned about the harmful effects of the ultraviolet (UV) rays in sunlight, they're essential for the production of vitamin D in the body. Now, scientists are claiming that UV LEDs ...

In a darkened corner of Nanosys's suite here at CES 2025 in Las Vegas was a tiny watch-sized prototype display. At first ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Viosys (KOSDAQ: 092190), a leading compound semiconductor solution provider, announced that its ultraviolet LED Violeds technology – the world’s first UV LED ...

Featuring 4 LED light heads with a total of 288 watts of 395nm UV LED, the WALCD-4X24LED-UV LED light stand enables operators to position high intensity UV light on product surfaces to cure a wide ...

Scientists demonstrate the first direct germicidal effect with an ultraviolet LED source. A US collaboration has reduced levels of E.coli. bacteria in water by over five orders of magnitude using 280 ...

For a long time, offset lithographic pressrooms have been reaping the benefits of curing inks and coatings with ultraviolet (UV) radiation instead of drying them with spray powder and/or heat. The end ...

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 ...

UV light inactivates germs in drinking water. Until now, this disinfection process has typically relied on mercury-vapor lamps, which emit light in the UV spectrum. However, mercury is a toxic heavy ...

Researchers are developing ultraviolet LEDs that have the ability to decontaminate surfaces -- and potentially air and water -- that have come in contact with the SARS-CoV-2 virus. As COVID-19 ...
