摘要	Eu-complex organic electroluminescent (EL) devices with a double metal-mirror Fabry-Perot microcavity structure were constructed to increase luminance efficiency and to improve colour purity. By optimizing the device structure, bright pure red EL from the Eu3+ ion was obtained. The peak luminance of 1160 cd m(-2) at 19 V and CIE coordinates of (x = 0.675, y = 0.320) at 12 V were achieved in the cavity device. The narrow-band emission peak was not changed with increasing detection angle, and the colour saturation of the top 45 degrees-off normal EL emission was even better than that of top normal emission in noncavity devices, overcoming the emission colour blue-shift with increasing detection angle in traditional microcavity devices. It was more important that a significant improvement in EL quantum efficiency at high current density was observed in the cavity device and the increasing mechanism of the EL efficiency was also revealed, which should be mainly ascribed to the shortened lifetime of the excited state of the Eu3+ ion.
