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.

Electrode for electroluminescence and electroluminescent device using the same

An information recording medium ( ) comprises a base sheet ( ), a resin layer ( ) formed on the base sheet ( ) and having a holographic region ( ) provided with a diffraction grating ( ) in a regular or irregular arrangement, and a ferromagnetic thin film ( ) formed on the holographic region ( ) of the resin layer ( ). The ferromagnetic thin film ( ) has a specific magnetic characteristic dependent on a holographic pattern formed in the holographic region ( ). The magnetic characteristics of the ferromagnetic thin film are converted into signals corresponding to the holographic pattern.
