| dc.description.abstract | Refractive index based oxide ion polarizability, αO<inf>2</inf>-(n<inf>o</inf>), and optical basicity, Λ(n<inf>o</inf>), values are determined for B<inf>2</inf>O<inf>3</inf>, SiO<inf>2</inf>, P<inf>2</inf>O<inf>5</inf>, GeO<inf>2</inf>, TeO<inf>2</inf>, Ga<inf>2</inf>O<inf>3</inf>, As<inf>2</inf>O<inf>3</inf>, La<inf>2</inf>O<inf>3</inf> and Sb<inf>2</inf>O<inf>3</inf> single component glasses on the basis of their refractive index and density. Basicity values of 0.46 for B<inf>2</inf>O<inf>3</inf> glass, 0.53 for SiO<inf>2</inf> glass, 0.54 for P<inf>2</inf>O<inf>5</inf> glass, 0.80 for GeO<inf>2</inf> glass, 0.93 for Ga<inf>2</inf>O<inf>3</inf> glass, 1.02 for As<inf>2</inf>O<inf>3</inf> glass, 1.05 for TeO<inf>2</inf> glass, 1.11 for Sb<inf>2</inf>O<inf>3</inf> glass and 1.18 for La<inf>2</inf>O<inf>3</inf> glass are advanced. They are slightly higher than those obtained for simple crystalline oxides. Chemical bonding parameters such as the refractive index based interaction parameter, A(n<inf>o</inf>), and single bond strength B<inf>M-O</inf> are used to support the basicity data obtained. The correlation between the optical basicity, Λ(n<inf>o</inf>), and single bond strength B<inf>M-O</inf> of some Sb<inf>2</inf>O<inf>3</inf>, Bi<inf>2</inf>O<inf>3</inf> and TeO<inf>2</inf> containing glasses is studied. It is found that in general a decrease in A(n<inf>o</inf>) and B<inf>M-O</inf> is accompanied by Λ(n<inf>o</inf>) increase. The applicability of thye observed correlations to nonlinear optics is also discussed. | |
