Web18 mei 2006 · This doping strategy allows us to develop an AlN PIN (p-type/intrinsic/n-type) homojunction LED with an emission wavelength of 210 nm, which is the shortest reported to date for any kind of LED. The emission is attributed to an exciton transition, and represents an important step towards achieving exciton-related light-emitting devices as …
Web15 dec. 2024 · Mercury lamps emit sufficient energy above 300 nm at only certain wavelengths, which are very useful for monochromatic irradiation, and so the spectrum … WebUV LED lamps radiate a different emission spectrum from the one of traditional mercury UV lamps. Emission peak is always very selective, focused on precise wavelengths, which generally are 365,385, 395, 405 nm (±5nm). So it must be considered a virtually monochromatic radiation.
