US team research and development of efficient deep UV LED, the industry's lowest wavelength record

University of Cornell research team, the latest research and development of a small and more environmentally friendly deep ultraviolet LED light source, and hit the industry's deep-UVLED minimum wavelength of the record.

The researchers used the atomic level control interface of gallium nitride (GaN) and aluminum nitride (AlN) single-layer film for the reaction area, the successful launch of the wavelength between 232 to 270 nm deep ultraviolet LED. This 232 nm deep UV, the highest use of gallium nitride for the luminescent material, the light emitted by the wavelength of the shortest record. The previous record was set by the Japanese team at 239 nm.

After successfully improving the luminous efficiency of the deep UV LED, the research team's next step is to integrate the light source into the device and move towards the goal of listing. Deep ultraviolet light applications include food preservation, counterfeiting, photocatalyst, water purification and so on.
