摘要

•The extrinsic photoconduction effect is successfully observed in Sb2Se3 for the first time.•Flexible extrinsic Sb2Se3 photodetector exhibits a broadened detection wavelength from 1050 to 1650 nm.•Extrinsic Sb2Se3 photodetector demonstrates fast response speed (rise of 9 µs and fall of 11 µs), high linear dynamic range (LDR, 98 dB), and wide -3dB bandwidth (163 kHz) at 1300 nm.
