Bismuth oxide (Bi₂O₃)-based glasses showing outstanding properties such as high linear refractive indices, low glass transition temperatures, and high third-order nonlinear optical susceptibilities are promising materials for low temperature melting and photonic device applications. The present article reviews the current status of the electronic polarizability in Bi₂O₃-based glasses with glass-forming oxides and modifiers through the refractive index-based optical basicity Λ(n_o) and interionic interaction parameter A(n_o) in to understand deeply the uniqueness of Bi₂O₃-based glasses among other oxide glasses. The values of Λ(n_o), and A(n_o) in some Bi₂O₃-based glasses were estimated newly in this article. It was clarified that Bi₂O₃-based glasses exhibit an extremely strong basic nature with Λ(n_o)∼1.15 and extremely weak chemical bond strength with A(n_o)∼0.01 Å⁻³ among oxide glasses, being more basic compared with TeO₂-based glasses with Λ(n_o)∼1.0 and A(n_o)∼0.03 Å⁻³. The outstanding properties of Bi₂O₃-based glasses were discussed from the viewpoints of electronic polarizability and weak chemical bond strength.
