摘　　要：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.
