By using the nanorods and nanosheets bismuthous sulfide materials, we report the successful fabrication of a new type of photodetector by the method widely used for solar cells. The photodetector revealed good properties for laser beam of 1024nm. The photoconductive properties of both samples were also studied by configuring the samples as photodetectors, exhibiting different photosensitivity. The results indicate the nanorods materials have higher photosensitivity than the nanosheets materials. Our results imply that the new type of photodetector is prospective candidate for high-performance photodetector.
