✦ Synopsis
In this paper, we introduce the optical electronegativity Dw à glass to predict basic properties of binary oxide glasses. Optical electronegativity Dw à glass of numerous binary oxide glasses has been evaluated on the basis of two different properties: the linear refractive index n and energy gap E g , which have demonstrated remarkable correlation. Furthermore, we also calculate the refractive index n through the energy-gap-based optical electronegativity Dw à E , and obtain a perfect linear correlation between the calculated refractive index n cal and the n 0 values of Dimitrov and Komatsu. The average electronic oxide polarizability a O 2À and the optical basicity L of binary oxide glasses have been estimated on the basis of the optical electronegativity Dw à glass calculated from the refractive index n. The estimated values are in good agreement with the available experimental data. The present method needs only one original experimental parameter to estimate the optical electronegativity Dw à glass , which is the refractive index n.
