Highlights: • Bi{sub 2}S{sub 3} nanorods and nanoflowers flexible laser detectors have been fabricated successfully. • The photoelectric properties were studied upon 808 nm and 980 nm laser beam irradiation. • Bi{sub 2}S{sub 3} nanorods flexible photodetector exhibits higher LDR value than other Bi{sub 2}S{sub 3} based photodetectors. - Abstract: Rod-like and flower-like bismuth sulphide semiconductor nanomaterials were large-scale synthesized and applied for flexible near-infrared laser detectors and visible light photodetectors. The nanorod-based flexible laser detectors have high photoresponse characteristics to 808 nm and 980 nm laser light, and their switching ratio were calculated to be 9.2 and 23.6 times, respectively. The flexible laser detectors exhibit good linear current characteristics, photo-sensitivity dependence of light intensity. Especially, the flexible nanorod-based photodetector has high LDR (linear dynamic range) value of 19.60 dB. Furthermore, the Bi{sub 2}S{sub 3} nanorods based visible light photodetector exhibits higher LDR value than other Bi{sub 2}S{sub 3} based photodetectors.
