Study on BaO-Bi2O3-B2O3-SiO2 Glasses in Material Engineering with Electronic Polarizability and Optical Basicity

Abstract

Bismuth/barium-containing crystals have attracted much attention in application of material engineering because of their importance for the development of nonlinear optical (NLO) information processing technology. Compared to crystals, glasses have shown many advantages in the material engineering, such as easier shaping in casting procedures, low production cost and high thermal and chemical durability. Furthermore, there is a close relationship between NLO and polarizability α and optical basicity Λ for the glasses system. Prompted by these interests in application of material engineering, we reported new data of α and Λ of BaO-Bi2O3-B2O3-SiO2 glasses system (G-BBBSO) for the different wavelength range (480, 546.1 and 643.8 nm). The results suggested that the G-BBBSO have a high polarizability and optical basicity, that is, the glasses system have potential application in material engineering.
