Research On LED Paves Way For UV Disinfection Technology

Research taking place at North Carolina State University may reportedly lead to a novel was of UV Disinfection Technology using LEDs. The LEDs have got aluminum nitride (AlN) as a semiconductor, due to which the material is able to manage a large amount of power, while generating light in a broad spectrum of colors in the UV range. Still, technologies that employ AlN LEDs to generate UV light have been restricted since the substrates that formed the base of these semiconductors assimilated wavelengths of UV light critical to the applications in sterilisation and water-treatment purposes.

Some researchers from North Carolina and Japan claim to have a solution to this problem. With computer simulation, they established that the trace carbon atoms in the crystalline structure of the AlN substrate were the reason most of the UV light got absorbed. Removing the carbon was key to substantially better the amount of UV light passing through the substrate. At present, HexaTech is developing the commercial technology based on this very research.
