The Japanese created a vacuum ultraviolet lamp

S. ONO/Nagoya Institute of Technology (NITech) a Team of researchers in Japan has developed a light bulb that emits ultraviolet light at short wavelengths, ever recorded for such a device, from 140 to 220 nanometers. Such a vacuum UV light extremely useful for industrial applications from sterilizing medical devices to cleaning semiconductor. High energy light upon impact splits the oxygen molecules on the surface, they generate highly reactive oxygen radicals, which can completely destroy any microbes contaminating that surface.





Existing commercial vacuum UV lamps are bulky and expensive. They require a lot of energy, emit large amounts of heat, have short lifetimes and contain toxic gasses that can pollute the environment and harm people. The new lamp avoids those issues because it is made with solid phosphor thin film of KMgF3, which is easy to manufacture, does not require use of toxic and expensive rare-earth elements.Shingo Ono of the Nagoya Institute of technology said: "Our lamp is a promising light source in terms of a lifetime, size, heat conduction and stability."
