Electroluminescent device comprising a transition metal oxide doped with a trivalent rare earth element

摘要: An electroluminescent device includes a layer including transition metal oxide doped with trivalent rare earth metal. The has the general formula, Mxi(MiiOy)z where Mi is Group IIA element or group IIIB element, Mii metal, O oxygen and subscripts x, y z denote number of each elements depending on valences particular used. may be in form single crystalline body particles dielectric medium. A pair spaced contacts are provided layer. For one blocking contact other an ohmic contact. which medium, both contacts. Light emitted from when current applied through between contacts; DC being used for AC
