英文摘要: Abstract(#br)Sm doped CeO 2 (Sm = 0%, 2%, 4%, 6% and 8%) nanoparticles have been synthesized by sol-gel method for spintronics and photodegradation applications. Structural properties were studied using X-ray diffraction that showed single-phase crystalline nature with some structural distortions. Raman spectroscopy was employed to study the defects where longitudinal optical mode confirmed the presence of defects in the form of oxygen vacancies. Magnetic studies infer that saturation magnetization (M S ) increased with Sm doping from 0.36 × 10 −3 emu/g for pure CeO 2 to 15.8 × 10 −3 emu/g for Sm 6% and then, decreased for Sm 8%. Reported results also demonstrated the excellent photodegradation of UV-irradiated rose bengal dye. X-ray photoelectron spectroscopy (XPS) was used to illustrate...
