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 alpha(O2-), optical basicity Lambda 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 alpha(O2-) and Lambda increase gradually with increasing wave number, and A decreases with increasing wave number. Furthermore, close correlations are studied among alpha(O2-), Lambda, 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 alpha(O2-), Lambda and A values. (c) 2006 Elsevier B.V. All rights reserved.
