ABSTRACT:
Devices which emit in the visible region having a metal oxide barrier layer, e.g. magnesium oxide or beryllium oxide, and having a corresponding metal electrode, i.e., a magnesium or beryllium electrode, in addition to a silver electrode are stable at room temperature. The emitted light spectrum is dependent on the voltage applied to the device which emits an orange or green appearing light for the Mg and Be junctions, respectively.
