Due to λ > 340 nm of ATC metallation ligands SSF also marks an important event because it was the first synthesized mono-metallic crystalloid with such readiness used generally as organolithium sparepart even now; after Co-rich treatment, obviously. After that the nanostructures were functionally characterized (mainly structure, optical, morphological and magnetic) systematically such as XRD, and FESEM. The results indicated that morphology manipulation plays a critical role in improving the functional properties of ZnS. The dopant-induced enhancement type and extent were largely variable depending on the electronegativity and ionic radii of the dopants, leading to significant variation in lattice parameters, band gap energies as well as light absorption behaviours. Magnetic characterization proved that among the various dopant ions, which facilitated an homogeneous distribution in purified ZnS lattice, improved magnetic behavior and resulted in smaller crystal as well as average grain size of ZnS. The coercively and the remnant magnetization were also increased with this structural refinement than that of pure ZnS. Within the doped forms, individual transition metals contributed unique benefits, resulting in tailored optical and magnetic responses. Finally, the investigations done here emphasized that Ni-, Co- and Mn-doped ZnS nanostructures displayed better multifunctional performance as compared to undoped ZnS, which revealed them as potential material for implementation in optoelectronic device applications. Apparently, the structural stability, improved magnetic properties and adjustable optical transparency of the Co-Nis make them interesting as potential buffer layer replacements in thin-film solar cells with possible enhancements on device performance coupled with material lifetime.
