The present study focuses on the structural, optical and magnetic properties of Sm doped
ZnO at very dilute concentrations (< 3%). These compounds have been synthesized by a
solid state reaction method after prolonged mixing by ball milling and characterized by X-ray
diffraction (XRD), scanning electron microscopy (SEM), optical spectroscopies (such as UV-
Vis, photoluminescence (PL) and Raman) and magnetization methods (M–H). The XRD
results show a small change in lattice parameters due to Sm doping in hexagonal wurtzite …
