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 forthe Gd-doped SnS powder proved the formation of an orthrhombic crystal structure. The SEM study reveals theparticles’ surface altered by introducing the Nd and Gd element into the SnS materials. Undoped and doped SnSmaterials have ferromagnetic characters detected, along with the distinct coercive force and intense magnetizationrevealed by VSM study. Significantly reduced band gap values have been observed for doped SnS in the opticalabsorption spectra. The antibacterial activity
of prepared materials was tested, and the results have been discussed indetail.
