K shell X-ray fluorescence parameters of Co, Ni, Cu and Zn in phthalocyanine complexes

The influence of the chemical effects on σKα,β production cross-sections and Kβ/Kα intensity ratios of Co, Ni, Cu and Zn elements in the phthalocyanine complexes was investigated. The samples were excited by 59.5keV γ-rays from an 241Am annular radioactive source. K X-rays emitted by the samples were counted by an Ultra-LEGe detector with a resolution of 150eV at 5.9keV. We observed the effects of different ligands on the σKβ production cross-sections and the Kβ/Kα intensity ratios. These effects were interpreted according to the charge transfer process from the central atoms to the ligands. •This work considers the K X-ray fluorescence parameters of phthalocyanine complexes.•These parameters were obtained using EDXRF methods.•The results are in good agreement with theoretical and experimental values.
