Abstract The photorefractive effect was observed in poly(N-vinylcarbazole) composite films doped with electro-optic chromophore 2,5-dimetly-4(p-nitrophenylazo) anisole, plasticizer N-ethylcarbazole and different content fullerene C₆₀. Their two-beam coupling experiment was performed by using a cw He-Ne laser at 632.8nm. The two-beam-coupling gain coefficient as higher as 140cm^-1 was measured at poling dc electric field of 76V/μm and it was also found to be relied on the content of photosensitizer C₆₀.
