A group of researchers from the Institute of Ion Beam Physics and Materials Research at Forschungszentrum Dresden-Rossendorf in Germany has discovered that the rare-earth element europium can do something rare. When used in a silicon wafer as a dopant, it makes a metal-oxide semiconductor electroluminescent device that changes color from red to blue when the drive current changes from low to high. Although the group had worked with rare-earth dopants before, institute director Manfred Helm said that the results surprised its members, noting that some changes of intensity within the various...Read full article
