Preparation Ag₂S Nanorods and Nanoparticles via a Simple Chemical Method

Abstract:

Ag₂S nanorods and nonoparticles have been successfully prepared using chemical method. Silver nitrate with molar concentration of 0.1 M and thiourea with different molar concentration were used as a source of Ag⁺⁺ and S⁺⁺ ions, respectively. The pH of solution was in range of 10-11. Scanning electron microscopy (SEM) image showed that the nanorods length and diameter were 2.5-3 μm and 300-400 nm, respectively. X-ray diffraction results showed a monoclinic α-Ag₂S phase was obtained. The atomic ratio of silver and sulphur were found using energy dispersive spectroscopy (EDS) and it was 62.39% and 37.61%, respectively.
