bstract- In the present work, undoped and
Mn-doped ZnS nanoparticles (ZnS:Mn) were growth by the spin coated method at
room temperature. The concentration of the Mn ions was changed from 2 to 6%.
Different analytical techniques including were used to investigate the
influence of Mn concentration on optical properties of produced thin films. In
summary, the influence of Mn doping on the optical properties of un-doped ZnS thin
films was reported. These results were also compared to the ZnS:Mn thin films
produced by different techniques. In UV-Vis. studies, the band gap energy was
found to be 3.5–3.8 eV depending on the Mn doping ratio. In addition, undoped
and Mn-doped ZnS nanoparticles were theoretically performed as a cluster by
semi empirical calculations. In these calculations, the Zn₇S₇ and
Zn₅Mn₂S₇
were optimized as a hexagonal wurtzite phase structure by semi-empirical pm6
level. The theoretical band gaps for both molecules were calculated with same
method.
