Abstract

Wide set of experimental results on binding energy of photoelectrons emitted fromP2p,P2s, andO1score levels has been observed for inorganic phosphate crystals and the parameters were compared using energy differencesΔ(O1s-P2p)andΔ (O1s-P2s)as most robust characteristics. Linear dependence of the binding energy difference on mean chemical bond lengthL(P–O) between phosphorus and oxygen atoms has been found. The functions are of the forms:Δ (O1s-P2p) (eV) = 375.54 + 0.146 · L(P–O) (pm)andΔ (O1s-P2s) (eV) = 320.77 + 0.129 · L(P–O) (pm). The dependencies are general for inorganic phosphates and may be used in quantitative component analysis of X-ray photoemission spectra of complex oxide compounds including functional groups with different coordination ofPandOatoms.
