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 ...
