Abstract
For the performance of the photorefractive (PR) effect, materials must exhibit the photoconductivity (PC) and the linear electro-optic response (EO) simultaneously. To supply the PC property in PR composites, a photosensitive molecule and a transport agent are necessary. The photogeneration quantum efficiency (PGQE) is an important parameter in the photoconductivity property of a material, which has been regarded to follow the Onsager model or the Braun modified Onsager model. In the paper, we presented the experimental demonstration of the PGQE in the composite of C60:poly(N-vinylcarbazole) (C9 60):PVK)
