摘要: An experimental and theoretical investigation of defect modes in tin-doped cupric oxide (Sn-doped CuO) nanoparticles synthesized via a one-step solid-state reaction was reported. The mode at 455 cm-1 due to Sn doping CuO nanoparticles, calculated using molecular model, compared with the value 458 obtained from FTIR vibrational spectrum. Debye-Waller factor (DWF) determined Rietveld refinement XRD pattern Wilson’s plot, results were discussed on basis number surface atoms thermal vibrations. effect upon DWF Sn-doped also discussed.
