Abstract
A remarkable photo-induced illumination memory was observed in an iodine-doped conductive polymer/poly(N-vinylcarbazole) (PVK)-trinitrofluorenone (TNF) double-layered system. The memory was measured as a lowering of charge acceptance and investigated as a function of various parameters such as the wavelength, the intensity and the exposure of incident light. It was found that the interface between the conductive polymer containing iodine and the photoconductor is responsible for this phenomenon and the memory effect is caused by carriers generated in the photoconductor. The exposure needed for lowering the charge acceptance to half the initial value was about 30 µJ/cm2. The memory effect was also observed in an organic iodide-dispersed PVK/TNF system though its sensitivity was much lower than that of the aforementioned polymer-using system.
