Evidence for the role of organic layers in photoconductivity of organic/ inorganic hybrid nanosheets as prepared by Langmuir-Blodgett methods

摘要

By measuring the photoconductivity of hybrid LB films of exfoliative layered niobate and octadecylamine, it was evidenced that the film underwent a transition from an insulator to a photosemiconductor during photo-modification treatment by UV light, which was rationalized in terms of the direct contact of inorganic nanosheets achieved by the elimination of organic layers.
