The K shell production cross-sections and K beta to K alpha X-ray intensity ratios of peripherally and non-peripherally tetra-substituted zinc (II) phthalocyanine complexes were determined using energy dispersive X-ray fluorescence spectrometry (EDXRF). The effect of substituent position on these parameters was also investigated. The complexes were excited by 59.5 keV gamma-rays from an Am-241 annular radioactive source and K X-rays emitted by the complexes were counted by an Ultra-LEGe detector with a resolution of 150 eV at 5.9 keV. The experimental results of the zinc phthalocyanines having the same ligand substituted peripheral and non-peripheral were compared with each other, theoretical, and experimental values of pure zinc.
