▎ 摘  要

A photo-thermal/catalytic reduction lithography (PRL) approach for the fabrication of photoconductive patterns by 300 W Xe lamp illumination of the (PDDA/GO/PDDA/TiO)(20) hybrid films formed through layer by layer (LBL) assembly technique has been reported. High quality (PDDA/GO/PDDA/TiO)(20) hybrid films were fabricated on the glass substrate through alternative LBL self-assembly with graphene oxide (GO), titania (TiO) nanosheets, and poly(diallyldimethylammonium) (PDDA). Then, the photoconductive pattern was fabricated by illuminating the hybrid film equipped with a pre-designed aluminium foil as the shadow mask. The "on-off" photoconductive response of the fabricated pattern was directly tested due to the photo-electro conversion role of TiO nanosheets and electronic transportation of reduced GO (RGO) nanosheets, which shows a high photocurrent generation and good reversibility.
