The average electronic oxide polarizability α02− of numerous single component oxides has been calculated on the basis of two different properties: linear refractive index n0 and energy gap Eg, which have demonstrated remarkable correlation. The optical basicity Λ of the oxides has been estimated on the basis of average electronic oxide polarizability calculated from the refractive index Λ(n0) and the energy gap Λ(Eg). A good agreement has been observed between the optical basicity data obtained using independent initial quantities. The simple oxides have been separated into three groups according to the values of their oxide polarizability. The α02− values (above 3 A) obtained for PbO, Sb2O3, and Bi2O3 have been attributed to the high cation polarizability and the presence of a lone pair in the valence shell of the cation.read more

Classification of Simple Oxides: A Polarizability Approach
TL;DR: In this article, a simple oxide classification has been proposed on the basis of correlation between electronic polarizabilities of the ions and their binding energies determined by XPS, taking into account the values obtained on refractive-index- or energy-gap-based oxide ion polarizability, cation polarIZability, optical basicity, O 1 s binding energy, metal (or nonmetal) binding energy and Yamashita-Kurosawa's interaction parameter of the oxides.
