Prospects of far-UVC LED technology

This presentation will provide an overview of the state-of-the-art in the development of AlGaN-based far-UVC-LED technologies. We will explore origins for the observed decline in the external quantum efficiency (EQE) with decreasing emission wavelength and present different approaches to improve the RRE, CIE, and LEE of UV light emitters. We will also discuss design aspects for far-UVC irradiation systems and provide an outlook of future prospects of far-UVC-LED device technology as well as the potential for a wider use of far-UVC sources in applications like room air disinfection.
