Breakthrough in GaN Core-Shell Nanowire UV LED Technology Achieves Fivefold Intensity Increase

Researchers at the National Institute of Standards and Technology (NIST) have developed innovative nanowire-based ultraviolet (UV) LEDs capable of producing light intensity five times greater than previous designs, thanks to a streamlined shell structure. Utilizing a “p-i-n” core-shell design with aluminum-doped shells, this breakthrough enhances electron confinement, significantly improving electroluminescence. The development, which is detailed in the Nanotechnology Journal, positions these UV LEDs for pivotal roles in applications ranging from water purification to medical disinfection. NIST is collaborating with industry partners to integrate these advanced LEDs into micro-LED technology and scanning-probe tips, with plans for prototype demonstrations on the horizon.
