    • Disclosed are organic EL elements having high environmental stability as well as high luminous efficiency and luminance. In an organic EL element comprising a transparent anode, a hole-carrying layer, a light-emitting layer and an alloy cathode consisting of a first metal Li and a stabilizing second metal Al, all laminated on a substrate, the concentration of the first metal Li contained in the alloy region with a predetermined thickness from the interface between the alloy cathode and the organic layer is controlled to a minute amount ranging from 0.005 wt. % to 0.3 wt. %. In another organic EL element comprising a transparent anode, a hole-carrying layer, a light-emitting layer and an alloy cathode consisting of a first metal Sr and a stabilizing second metal Mg, all laminated on a substrate, the concentration of the first metal Sr contained in the alloy region with a predetermined thickness from the interface between the alloy cathode and the organic layer (light-emitting layer or electron-carrying layer) is controlled to a minute amount ranging from 10 wt. % to 40 wt. %.

    • An organic electroluminescent device comprises an anode, a positive-hole transport layer made of an organic compound, an emitting layer made of an organic compound, and a cathode which are layered in sequence, further comprising an electron-injecting layer containing at least one of alkaline earth metal oxides and disposed between the emitting layer and the cathode. This device emits light at a high luminance and a high efficiency upon application of a low voltage together with reduction of the decrement of luminance in the running of emitting light of the device. Selection scope for cathode materials is expanded because of the device is free from the restriction of a low work function for the cathode layer. The cathode can be made a transparent electrode such as ITO. Anode and cathode lines may be formed with low resistance material. As a result, emitting efficiency and life time of the device is improved.
    • 一种有机电致发光器件包括阳极,由有机化合物制成的正空穴传输层,由有机化合物制成的发射层和依次层叠的阴极,还包括电子注入层,该电子注入层包含至少一个 碱土金属氧化物并且设置在发光层和阴极之间。 该装置在施加低电压的同时以高亮度和高效率发光,同时降低器件发射光的运行中的亮度减少。 阴极材料的选择范围扩大,因为该器件没有限制阴极层的低功函数。 阴极可以制成诸如ITO的透明电极。 阳极和阴极线可以用低电阻材料形成。 结果,提高了器件的发光效率和寿命。
