Nitride based High Efficiency Deep UV LED for Sterilization
Lack of clean water is one of the greatest problems presently affecting the health of the world’s population. The scale of this problem is evident in the fact that, in the developing world, a child dies every minute from a disease related to contaminated
water. Even in developed countries such as Saudi Arabia water pollution is a significant issue and utility companies are investing millions of dollars into researching new systems that would allow treating recalcitrant micropollutants, such as metaldehyde.
As AlGaN-based deep ultraviolet (DUV) LEDs emitting at 265-275 nm can be light sources capable of germicidal disinfection, they have recently attracted great scientific and commercial interest.
