Abstract: Sb2Se3 nanowires ([001] orientation) with a diameter of 100-200 nm and high aspect ratio were successfully synthesized at 180℃ for 10h by a facile non-aqueous polyol method, where home-prepared NaHSe alcohol solution was used as selenium source and PEG-400 served as an excellent solvent and structure director. The product was characterized by XRD, TEM, SAED, HRTEM, EDS and UV-Vis spectroscope, respectively. The effect of different polyols on the final product s morphologes was investigated. The results indicated that the PEG-400 played the key role in the crystal anisotropic growth and the non-aqueous polyol system provided a clean crystal growth condition.

Key words: Sb2Se3, nanowires, polyol process
