LOS ALAMOS, N.M., Feb. 28, 2012 — Inorganic LEDs that emit in the difficult-to-achieve ultraviolet range were produced by embedding nanocrystals in glass, a step toward using such devices in biomedical applications. Scientists at the Los Alamos National Laboratory, in collaboration with researchers at the University of Milano-Bicocca in Italy, developed the new inorganic UV LEDs by combining the chemical inertness and mechanical stability of glass with the property of electric conductivity and electroluminescence. Embedding nanocrystals in glass provides a way to create UV-producing LEDs for biomedical...Read full article

    electroluminescence
    The nonthermal conversion of electrical energy into light in a liquid or solid substance. The photon emission resulting from electron-hole recombination in a PN junction is one example. This is the mechanism employed by the injection laser.
