L shell X-ray fluorescence parameters of Pb in phthalocyanine complexes

•The L shell XRF parameters of Pb in the phthalocyanine complexes were investigated.•These parameters were obtained using EDXRF method.•The results are agreement with the theoretical values.

The L shell X-ray intensity ratios Li/Lα (i=l, β and γ), the production cross-sections σLi (i=l, α, β and γ) and the L3 subshell fluorescence yields ωL3 have been investigated for the element Pb in the phthalocyanine complexes. The measurements have been performed using an 241Am annular radioactive source and an Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV. The experimental values have been compared with the theoretical values of pure Pb element.
