Correlation among electronic polarizability, optical basicity and interaction parameter of Bi2O3–B2O3 glasses

For optical basicity and electronic polarizability, the previous studies basically concentrate on the wavelength range of the visible light region. However, heavy metal oxides glasses have a reputation of being good materials for infrared region. In this study, new data of the average electronic polarizability of the oxide ion αO2-αO2-, optical basicity Λ and Yamashita–Kurosawa's interaction parameter A of Bi2O3–B2O3 glasses have been calculated in a wavelength range from 404.66 to 1083.03 nm. The present investigation suggests that both αO2-αO2- and Λ increase gradually with increasing wave number, and A   decreases with increasing wave number. Furthermore, close correlations are studied among αO2-αO2-, Λ, A and refractive index n in this paper. Particularly, it has been found that a quantitative relationship between electronic polarizability and optical basicity is observed in a wavelength range from 404.66 to 1083.03 nm. Our present study extends over a wide range of αO2-αO2-, Λ and A values.
