Effect of Bi2O3 on physical, optical and structural properties of boron silicon bismuthate glasses

Abstract: The lead-free boron silicon bismuthate glasses were investigated in terms of their physical, optical and structural properties. The physical properties of these glasses have been explored by compositional variation of X-ray diffraction (XRD), differential thermal analysis (DTA) and density. The optical properties of theses glasses have been investigated by UV–Vis and mid-infrared transmittance spectra, and refractive index. The structure of these glasses has been characterized by infrared (IR) absorption and Raman spectra. [Copyright &y& Elsevier]
