摘要: Photoconductive properties of a polymer designed to be photorefractive are investigated. The polymer is composed of photoconducting PVK [poly(n-vinylcarbazole)], photosensitizing TNF (2, 4, 7-trinitro-9-fluorenone), and optically nonlinear DANS (4-N, N-dimethyl-4′-nitrostilbene). The electric-field dependence and λ dependence of its photoconductivity and photocarrier generation efficiency have been measured. And preliminary four-wave mixing experiments have been carried out.
