Researchers at the University of California, Santa Barbara (UC Santa Barbara) are developing ultraviolet (UV) LEDs for decontaminating surfaces and potentially air and water that have come in contact with the SARS-CoV-2 virus.
UVC is the UV wavelength that is used for purifying air and water and for inactivating microbes. Unlike UVA and UVB wavelengths, UVC can be generated only through inorganic processes.
The materials scientists at UC Santa Barbara’s Solid State Lighting & Energy Electronics Center (SSLEEC) were already working on UVC LED technology when the COVID-19 pandemic gained momentum. The researchers fabricated high-quality deep-UVC LEDs by depositing a film of the semiconductor alloy aluminum gallium…READ MORE
