  • Conductive electron injector for light-emitting diodes
    Patent number: 5608287
    Abstract: An electroluminescent device (10) has a bottom electrode layer (13) disposed on a substrate (11) for injecting electrons into an organic layer (15); and a top electrode (17), such as ITO, disposed on the organic layer for injecting holes into the organic layer. The bottom electrode is formed of either metal silicides, such as, rare earth silicides, or metal borides, such as lanthanum boride and chromium boride having a work function of 4.0 eV or less. The electrodes formed from either metal silicates, or metal borides provide protection from atmospheric corrosion.
