Milliwatt power 233 nm far-UVC LEDs on sapphire substrates

FBH research: 22.09.2020

AlGaN-based far-ultraviolet light-emitting diodes (far-UVC LEDs) with emission below 250 nm are an attractive solution for a number of applications such as monitoring of gas concentrations, and measurement of nitrate in water. Recently, the possibility of using these far-UVC LEDs to destroy microorganisms without allowing resistances to develop has drawn particular interest. Their light does not penetrate into the living layers of the skin. It is therefore expected that the skin will not be harmed at all or will be damaged so little that the natural repair mechanisms compensate for the effect. However, fabrication of high-power devices at wavelengths below 250 nm is challenging.

Combating Pathogens Using UVC Light

Press Release Technische Universität Berlin, 27 August 2020

Technische Universität Berlin

According to estimates, multi-resistant hospital germs kill between 10,000 and 20,000 people in Germany each year. Standard medicines and antibiotics are often already ineffective. As part of the Joint Lab GaN Optoelectronics, researchers at the Ferdinand-Braun-Institut, Leibniz Institut für Höchstfrequenztechnik (FBH) and Technische Universität Berlin (TU Berlin) have developed special LEDs, which emit UVC light at wavelengths of around 230 nanometers (nm). “The goal is to use these LEDs to combat multi-resistant germs,” says Professor Dr. Michael Kneissl, head of the Workgroup Experimental Nanophysics and Photonics at TU Berlin.

What UV LEDs can do for drinking water disinfection

TZW News, 29.07.2020

TZW: DVGW - Technologiezentrum Wasser

Due to the rapid technical progress of LEDs in the UVC range between 240 and 280 nm, the interest in UV LEDs as an alternative to conventional mercury-containing systems for water treatment has increased in recent years. The Federal Ministry of Education and Research (BMBF) supported the basic project "GEntLED-UV" on the topic "UV-LED". Within this joint project, TZW could determin how efficient different wavelengths act on undesired microorganisms in the water. Technical aspects such as service life and monitoring of the LED module in comparison to the established low and medium pressure mercury vapour lamps were also taken into account.
