Close Relationship

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.

Abstract A series of europium doped Na2O-B2O3-SiO2, PbO-GeO2 and ZnOTeO2 glasses was investi-gated by means of151 Mössbauer spectroscopy. The distortion of the Eu sites has been evaluated in the Na2O-B2O3-SiO2 glasses by means of the quadrupolar interaction parameter and the asym-metry parameter; the disorder has been estimated by the line width. The occupancy of the sites in the borosilicate glasses is discussed. The correlation of the isomer shift with the optical basicity of the glass is discussed in terms of the degree of covalence of the Eu-O bond.
