Сучасний стан спектральних характеристик ультрафіолетових світлодіодів

Abstract

Ultraviolet irradiation is one of the most promising branches of science and technology in an effort of disinfection of living quarters and storage facilities. The use of ultraviolet energy is becoming increasingly important because it is one of the main methods of inactivation of viruses, bacteria and fungi. A promising area of this technology is the use of radiation with a wavelength of 200-220 nm (far-UVC), which is less dangerous for the human body while retaining disinfectant properties. Far-UVC sources are, commonly, KrCl excimer lamps, but modern far-UVC LEDs with aluminum nitride (AlN) may be the best solution in the long-range outlook.
