Facile microwave-assisted synthesis of uniform Sb2Se3 nanowires for high performance photodetectors

Yong-Qiang Liu,Meng Zhang,Feng-Xia Wang,Ge-Bo Pan

A facile and rapid microwave-assisted method was developed to synthesize uniform single-crystalline Sb2Se3 nanowires in high yields. The as-prepared Sb2Se3 nanowires were directly used for fabricating prototype photodetectors. The device displayed a remarkable response to light intensity with an on/off ratio larger than 150, short response/recovery times (0.2/1.2 s), and long-term durability. The high sensitivity and robust environmental stability of the devices demonstrate the bright prospects for Sb2Se3 nanowires in highly efficient photodetectors for practical use.
