The Ferdinand-Braun-Institut has fabricated micro light-emitting diodes in the UV spectral range. The tiny LEDs can be densely packed to form high-resolution arrays. Berlin, 11.07.2022 Researchers at the Ferdinand-Braun-Institut (FBH) in Berlin have successfully produced the first prototypes of micro-LEDs that emit in the ultraviolet spectral range (UVB). The micro-LEDs with 310 nanometers (nm) emission wavelength feature a small size of the emitting area with diameters down to 1.5 micrometers (µm). This is hundreds to thousands of times smaller than ...

The Franco-German satellite MERLIN is due to be launched into space in 2025 to measure the methane concentration in the Earth's atmosphere - a milestone in climate research. Important components of the LiDAR measurement system come from the Ferdinand-Braun-Institut in Berlin, which has now delivered the required laser diode benches to the project partner. The MERLIN mission aims to better understand the effect of the greenhouse gas methane on global warming. A radar-like laser system on the satellite measures natural and anthropogenic methane emissions: The...

Berlin-based Ferdinand-Braun-Institut (FBH) and its spin-off UVphotonics have designed and developed a versatile irradiation system for surface treatment. The modular system can be flexibly equipped with its in-house developed UV LEDs and commercially available UV, visible and infrared LEDs, meeting the demands for different targeted emission spectrum. (Image: FBH) For disinfection purposes it can be equipped with LEDs emitting at 265 nm to eliminate germs on surfaces of daily objects such as mobile phones and reusable masks as well as menu cards in restaura...

German research institute the Ferdinand-Braun-Institut (FBH) and Technische Universität Berlin (TUB) have developed UV LEDs emitting UV light that is safe to the skin. The achievement has yet commercially available but will be tested in medicine research centers in Germany. The FBH and TUB worked under the framework of their Joint Lab GaN Optoelectronics and created LEDs that deliver far UV light at wavelengths around 230 nm and provide more than 1 mW output power. According to the FBH, the light does not penetrate into the living layers of...

UVphotonics and Ferdinand-Braun-Institut (FBH) are presenting novel UV LED developments with emission wavelengths from 330 nm to as low as 230 nm at Photonics West 2020.
