Title: Synthesis of Sb{sub 2}S{sub 3} nanowall arrays for high performance visible light photodetectors

Highlights: • Sb{sub 2}S{sub 3} nanowall arrays have been synthesized via a facile polyol refluxing process. • We fabricated Sb{sub 2}S{sub 3} rigid and flexible photodetectors successfully. • The photoelectric properties were studied upon visible light irradiation. • The rigid photodetector exhibit excellent photoconductive performance. - Abstract: By using a facile polyol and template-free refluxing process, we report the successful synthesis of Sb{sub 2}S{sub 3} nanowall arrays (NWAs) on the surface of FTO substrate. The as-synthesized samples were characterized by SEM, TEM, XRD and UV–vis DRS. The NWAs-based photodetector exhibits linear photocurrent characteristics, high stability, excellent reproducible properties, low LDR (linear dynamic range) value of 8.6 dB, fast response time of 0.52 s and recovery time of 1.11 s. The flexible photodetector was also fabricated by simply transferring the NWAs to a transparent PET substrate; it revealed good flexibility and stability. Our results imply that Sb{sub 2}S{sub 3} NWAs are prospective candidates for high-performance nanoscale optoelectronic devices.
