Silver antimony sulphide (AgSbS 2 ) flower-like nanostructures were successfully synthesized by a simple wet chemical method from silver nitrate (AgNO 3 ), antimony chloride (SbCl 3 ) and thioacetamide (C 2 H 5 NS) in ethylene glycol (EG) without using any surfactant. In this research, the first simple wet chemical method was developed for synthesizing AgSbS 2 nanostructures that very simple, rapid, surfactant-free, low-cost method and large-scale-production. X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) illustrate that the as-prepared products were cubic AgSbS 2 flower-like nanostructured clusters. The energy gap (E g ) was determined by UV-visible absorption to be 1.80 eV, including 688 nm emission wavelength by photoluminescence (PL) spectroscopy.
