Vacuum ultraviolet lamp of the future created in Japan

A team of researchers in Japan has developed a solid-state lamp that emits high-energy ultraviolet (UV) light at the shortest wavelengths ever recorded for such a device, from 140 to 220 nanometers. This is within the range of vacuum-UV light—so named because while light of that energy can propagate in a vacuum, it is quickly absorbed by oxygen in the air.
