Abstract(in English) We have applied the idea of hybridizing of organic and inorganic materials to the organic electroluminescent (EL) device. The mixed thin films of diamine (TPD) and MgF_2 are confirmed to be thermally stable. The organic EL devices fabricated by using the mixed thin film as the hole-transporting layer, and the emitting layer of tris-(8-hydroxyquinoline) aluminum (Alq) show bright green emission with 2600 cd/m^2 at a voltage of 15 V. Typical luminous efficiencies are about 0.3 lm/W at a current density of 40 mA/cm^2. The thermal stability of the organic EL device is greatly improved compared with the conventional organic EL device. The organic EL devices can be fabricated even at high temperature over 100℃. It is also found that the multi-layer type superlattices of TPD and MgF_2 act as the hole-transporting layer.
