Abstract
In this work Mn<sup>2+</sup>-doped ZnS nanoparticles were prepared by chemical co-precipitation method at room temperature. The structural and optical properties of the ZnS:Mn nanoparticles were determined by XRD, SEM, UVVisible and FL analyses. XRD analysis showed the sample prepared were in cubic phase with particle size in the ranges 12nm-25 nm. The SEM analysis reveals the growth of nanoparticles agglomerated in different shapes and orientations. In UV_Visible study the band gap energy corresponding to the absorption edge estimated are found to be 4.4~ 4.3eV which shows the large blue shifting from the bulk band gap 3.6eV of ZnS. The FL peak analysis reveals the strongest absorption at around 329nm which is fairly blue shifted from the absorption edge of the bulk (345nm). Thus Mn incorporated into ZnS nanoparticles results in changing its morphological, structural and optical properties.
