Photoconducting films of polyvinylcarbazole(PVK) and zinc phthalocyanine(ZnPc) doped with fullerenes(a mixture of C60 and C70) were prepared and their photoconductive properties were measured.Surface potential measurements showed that the photosensitivity of fullerene-doped photoreceptors is remarkably enhnced,compared to that of the undoped materials.The photoconduction mechanism and the role of fullerene in the charge generation process are roughly discussed.
