UV LEDs are rapidly becoming commercialized, specifically used for industrial curing applications and medical/biomedical uses. Until recently, the lower wavelength limitation for high-efficiency die was at 390nm. It has been moved to 340nm and further developments over the next few years will likely see the commercialization of high efficiency die in the 320nm region. The material primarily used for UV LEDs is gallium nitride/aluminum gallium nitride (GaN/AlGaN). At this time the technology does not yield high power LEDs shorter than 360nm and the market is unsettled as several companies are moving to improve their processes.
