ABSTRACT:
The present invention provides an electrode for electroluminescence for use in electronic devices including organic electroluminescent devices and a process for producing the same, in which interfacial electric characteristics, such as work functions, can be easily controlled. The process for producing an electrode for electroluminescence comprises the step of diffusing an additive element for an electrode into the electrode and/or the step of developing surfactant properties of the additive element for an electrode.
