Les photoconducteurs organiques (OPC) constituent un sujet important de recherche et de développement pour l'électrophotographie de haute qualité. En utilisant la mesure de la génération optique de seconde harmonique induite par un champ électrique (EFISHG), nous pouvons sonder les processus de porteurs dans les processus électrophotographiques tels que la génération de porteurs de photos, la séparation de porteurs et le transport de porteurs pour la production d'images de copieur. Nous sondons ici sélectivement la génération et l’accumulation de charges dans la couche de génération de charges et la couche de transport de charges dans les OPC à structure multicouche. Nous avons étudié l'accumulation de charges dans des OPC sous illumination (longueur d'onde 635 nm) d'OPC de type double couche avec une structure de couche de transport de trous recouverte d'une couche de génération de charges. Le résultat a montré que l'absorption de la lumière produit efficacement des trous et des électrons libres dans la couche de génération de charge, suivi d'une accumulation excessive de trous à l'interface CG/CT en raison de l'effet photoconducteur de la couche CG. L’irradiation à courte longueur d’onde à 405 nm a induit un effet photovoltaïque. Ces résultats ont démontré que la mesure EFISHG est utile pour sonder sélectivement le processus porteur dans une couche de l'OPC multicouche et pour la discussion du processus porteur pour les productions d'images électrophotographiques.

Abstract: Organic photoconductors (OPC) have been an important research and development topics for high quality electrophotography. By using electric field induced optical second harmonic generation (EFISHG) measurement, we can probe carrier processes in electrophotographic processes such as photo carrier generation, carrier separation, and carrier transportation for copier image production. We here selectively probe charge generation and accumulation in charge generation layer and charge transport layer in multilayer structure OPCs. We studied charge accumulation in OPC under illumination (wavelength 635nm) of double-layer-type OPC with structure of hole transport layer coated on charge generation layer. The result showed that light absorption efficiently produces free holes and electrons in the charge generation layer, followed by excessive hole accumulation at the CG/CT interface due to photo-conducting effect of CG layer. The short-wavelength irradiation at 405nm induced photovoltaic effect. These results demonstrated that the EFISHG measurement is useful to selectively probe carrier process in one layer of the multilayer OPC and to the discussion of carrier process for electrophotographic image productions.
