In this study, full widths at half maximum (FWHM), asymmetry indexes, chemical shifts (ΔE) and Kβ-to-Kα X-ray intensity ratios of some pure metals (Mn, Fe, Cu and Zn) and some of their oxidized compounds (Mn2O3, Fe2O3, Fe3O4, Cu2O3 and ZnO) were investigated. The samples were excited by 59.54 keV photons emitted from a241Am radioisotopes source and characteristic K X-rays emitted from the samples were counted by a Si(Li) detector. The results have shown that the Kβ-to-Kα X-ray intensity ratios, asymmetry indexes, chemical shifts and full widths at half maximum (FWHM) values can change with sample sizes.
•No data is available about Full width at half maximum (FWHM), asymmetry index, chemical shift (ΔE), and Kβ-to-Kα X-ray intensity ratios for nano pure metal and nano oxygen compounds of Mn, Fe, Cu and Zn in literature.•The search is important in terms of understanding charge transfer phenomena in nano structure metals and compounds.•It was observed that the intensity ratios increased with the decrease in the number of valence electrons.
