An electroluminescent device with a three-layer structure was constructed using an intensely fluorescent material, 12-phthaloperinone derivative, for the emitter material. The cell structure of Mg-electrode/amorphous electron-transport layer/polycrystalline emitting layer/amorphous hole-transport layer/Au-electrode was constructed on a glass substrate. Yellow EL emission was clearly observed in normal room lighting at the dc bias voltage of 60 V. The emission intensity was proportional to the injection current over a wide current range of 10−7to 10−3A/cm2The EL intensity exceeded 1 μW/cm2at the injection current of 2 mA/cm2.
