Sonochemical synthesis of amorphous long silver sulfide nanowires

Long silver sulfide nanowires have been prepared via the thioglycolic acid (TGA)-assisted sonochemical method. The transmission electron microscope (TEM) and field emission scanning electron microscope (FESEM) images reveal that the nanowires have uniform width and length. The selected area electron diffraction (SAED) pattern indicates that the Ag2S nanowires are amorphous. Furthermore, the mechanism for the TGA-assisted sonochemical synthesis of Ag2S nanowires has been preliminarily presented.
