Water and Air Disinfection by AIN-based UV-LED

Crystal IS, Inc., the manufacturer of ultraviolet light emitting diodes (UV LEDs) based on aluminum nitride (AlN) substrate technology, will receive an $800,000 appropriation from the U.S. Department of Defense to advance development of large AlN crystals for effective deep ultraviolet sources.

AlN has been demonstrated to be superior for deep UV light-emitting applications of great importance to the military. The primary applications of UV-LEDs are as long-lasting, energy efficient, water and air disinfection devices. Crystal IS Inc is developing its deep UV-LEDs at 265nm, the peak germicidal wavelength.
