摘要：

Polarized light emission was observed in conjugated polymer electroluminescent diodes comprising rubbing-aligned poly(2,5-dinonyloxy-1,4-phenylenevinylene) as the emissive layer. By using 2-(4-biphenylyl)-5-(4-tert-butylphenyl)-1,3,4-oxadiazole dispersed in polystyrene as the electron-transporting/hole-blocking layer, the electroluminescence efficiency and the dichroic ratio of the electroluminescent light increased, resulting in polarized electroluminescence with a dichroic ratio of 4.0.
