Abstract  Poly-phenylquinoxaline is used as the electroluminescent( EL) materials to fabricate the thin film electroluminescent devices by the spin coating method. Doped with 1,3,5-triphenyl-2-pyrazoline,the EL spectrum of the devices is shifted to the blue-green region with its peak located at 465nm. The incorporation of a hole transport layer,poly-vinylcarbazole,will enhance the EL intensity,and the quantum efficiency is estimated to be 0.2%. Thus,the devices can be driven by either positive or negative bias(or ac voltage) even though the currentvoltage curve possesses a rectifying property.
