摘要: Abstract The effects of Ce doping on the structure, optical, oxidation, thermal and magnetic properties ZnS:Ce nanorods synthesized by a chemical co-precipitation method were reported. crystalline phase transformation from cubic to hexagonal structure was observed upon ZnS with Ce. Magnetic measurements showed existence room temperature ferromagnetism in Ce-doped nanorods. X-ray photoelectron spectroscopic (XPS) provided evidence for Zn—S bonds oxidation state near-surface region. Raman spectrum presence defects as well 5 wt.% doped substitution induced shape evolution studied using TEM. DRS spectra further validated incorporation Ce3+ ions. present study reveals that may find applications spintronic devices.
