有机电致发光器件的性能在很大程度上受用作阴极的金属种类的影响，因为在界面处形成的势垒高度取决于金属的电子和化学性质。根据三（8‐羟基喹啉）铝阴极与镁阴极界面电流的温度依赖性，认为该界面的载流子注入机制为零电场下势垒高度约为0.58±0.03 eV的热离子发射。当使用功函数较大的金属作为阴极时，势垒高度增大。电流密度也与界面的化学结构有关。
The properties of organic electroluminescence devices are largely affected by the kind of metals used as the cathode, because the barrier height formed at the interface depends on the electronic and chemical properties of the metals. On the basis of the temperature dependence of currents flowing through the interface between tris(8‐hydroxyquinolino)aluminum and a magnesium cathode, the carrier injection mechanism at the interface was ascribed to the thermionic emission with the barrier height of about 0.58±0.03 eV at zero electric field. The barrier height became larger when metals with larger work functions were used as the cathode. The current density was also found to be dependent on the chemical structure of the interfaces.
