Abstract

Nano-sized samerium oxide (Sm₂O₃) was synthesized successfully by the thermal decomposition of samarium nitrate in the presence of polyethylene glycol (PEG 2000). Synthesized nanoparticles of Sm₂O₃ were characterized by infrared spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The powder XRD pattern established the formation of body-centered cubic structure for Sm₂O₃. Sample possess spherical nano-sized particle with the average crystallite size ∼50 nm.
