摘　　要：Ternary semiconducting AgSbTe2 nanowire arrays were synthesized for the first time by using the direct-current electrodeposition technique.X-ray diffraction,scanning electron microscopy,energy dispersive spectrometry,and transmission electron microscopy analyses indicate that the nanowire arrays are high filling,ordered,single crystalline and the nanowires have a highly preferential orientation grown along the[100]direction.Annealing studies show that compared with other temperatures,annealing at 100°C can significantly increase the crystallinity of AgSbTe2 nanowires.The optical absorbance spectra of the AgSbTe2 nanowire arrays show that the optical band gap has a strong blue shift with decreasing the diameter of the nanowire.
