On the curve-fitting of XPS Ce(3d) spectra of cerium oxides by E. Paparazzo, Materials Research Bulletin 46 (2011)
In his letter , Paparazzo commented on interpretation of our results obtained using X-ray photoemission spectroscopy (XPS), which led us to conclusion that calcium doped CeO2 nanoparticles are more stable than undoped nanoparticles against processes stimulating reduction of Ce4+ to Ce3+, in particular, Ar+ ion bombardment . In his opinion, our interpretation ‘‘is largely unwarranted’’. Here we present additional arguments, based on the XPS data , that our conclusion mentioned above is indeed valid.
