UV micro-LEDs for sensing, production and communication

Source: ledinside.com, 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 conventional UV LEDs. The micro-LEDs can be closely packed with pitches down to 2 µm to form a two-dimensional array on a chip, resulting in high-resolution UVB emitting areas.
