摘要

Raman and infrared spectroscopies have been employed to investigate the xBi₂O₃–(65 − x)Li₂O–20ZnO–15B₂O₃ glasses in order to obtain information about the competitive role of Bi₂O₃ and B₂O₃ in the formation of glass network. IR and Raman spectra show that these glasses are made up of [BiO₃] pyramidal and [BiO₆] octahedral units. The formation of Zn²⁺ in tetrahedral coordination was observed. The average electronic polarizability of the oxide ion (tyle="text-decoration:none; color:black" href="/science?_ob=MathURL&_method=retrieve&_udi=B6W6W-4PT7X8F-3&_mathId=mml2&_user=1067359&_cdi=6609&_rdoc=13&_acct=C000050221&_version=1&_userid=10&md5=2b2295bda98f369cd68a463e3a3a97ac" title="Click to view the MathML source" alt="Click to view the MathML source">ttp://www.sciencedirect.com/scidirimg/entities/204e.gif" alt="greek small letter alpha" title="greek small letter alpha" border="0">_O²⁻), optical basicity (Λ), and Yamashita–Kurosawa's interaction parameter (A) were also examined.
