Aluminum Nitride Light Emitting Diodes with the Shortest Wavelength

"Engineers LED Roundup"

Towards Dioxin, PCB Decomposition Technology

Nippon Telegraph and Telephone Corporation (NTT) has observed light of 210-nm wavelength from aluminum nitride (AlN) light emitting diodes (LED). This is the shortest wavelength ever observed from any semiconductor, and confirms the long-held theoretical expectation that AlN could emit light in the deep ultraviolet (DUV) region ( 1* ) ( wavelengths from 200 to 300 nanometers; nano is 10-9). Light emitted at wavelengths in the DUV can efficiently decompose persistent toxic substances such as dioxin and PCBs ( 2* ), which have caused serious environmental problems all over the world.
