Hydrothermal synthesis of undoped and inner transition metals (neodymium (Nd), gadolinium (Gd)) doped tin monosulfide (SnS) nanostructures: Comparative study of the morphological, opto-magnetic properties and antibacterial performance

Undoped SnS, and Nd and Gd-doped SnS nanostructures were fabricated by hydrothermal approach. The XRD study for the Gd-doped SnS powder proved the formation of an orthrhombic crystal structure. The SEM study reveals the particles' surface altered by introducing the Nd and Gd element into the SnS materials. Undoped and doped SnS materials have ferromagnetic characters detected, along with the distinct coercive force and intense magnetization revealed by VSM study. Significantly reduced band gap values have been observed for doped SnS in the optical absorption spectra. The antibacterial activity of prepared materials was tested, and the results have been discussed in detail.

Automated summary
