Undoped and Mn-doped Ag2S nanoparticles were prepared using the chemical precipitation method. The effect of the Mn ion on both the structural and optical properties of Ag2S was investigated. The XRD pattern shows that Ag2S particles are crystalline with a monoclinic phase. Doping Mn+2 into Ag2S particles effects the crystalline structure and shifts the XRD peaks towards a longer diffraction angle. Debye-Schrrer’s formula was used to estimate the crystalline size of undoped Ag2S particles, and it was found to be 64.22 nm; however, the size was reduced after introducing Mn ions. FE-SEM images show that there is no effect of increasing dopant concentration on the particle shape and the majority are spherical. The optical properties of Ag2S show a significant enhancement after doping with Mn ions, and the enhancement increases as the Mn concentration increases.
