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

• 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.

The influence of the chemical effects on σKα,βσKα,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 59.5 keV 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 150 eV at 5.9 keV. We observed the effects of different ligands on the σKβσKβ 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.
