碩士 === 輔仁大學 === 物理學系 === 88 === The structure of lanthanum gallogemanate glasses were investigated by Fourier transform infrared (FTIR) spectroscopy. The effects of La2O3, Ga2O3 and GeO2 content on the properties and structure of the lanthanum gallogemanate glasses were evaluated. The IR spectra of these glasses suggest that Ga amd/or Ge might present tetrahedra (fourfold coordination) and octahedra (sixfold coordination). These glasses are transparent over frequencies ranging from the near ultraviolet (0.35μm) to the mid-IR (6~7μm) and show ionic bond behavior in their structure.
