Scientists develop UV LEDs made from nanowires

Investigators at the National Institute of Standards and Technology (NIST) and scientists from the University of Maryland and Howard University in Gaithersburg (MD) claim that they have formulated a technique to produce petite, highly efficient light-emitting diodes from nanowires that could be used in light-based nanotechnologies. This could be a massive step towards making of loads of nano-LEDs It is reported that the research group produced and tested more than 40 of these LEDs with similar emission properties and thermal stability. Further the reports concluded that new nanowires are “well-suited” for scaling to commercial production.

According to NIST, the nano-LEDs, made from gallium nitride (GaN), mostly emit ultraviolet light with a peak wavelength of 365 nm. The scientists suggested that this feature set could be useful for biomedical sensors, optical communications as well as future data storage technologies. However, they also said that enough visible light is generated “to see it glowing,” which could turn the nanowires into a general future light source as well.
