Ternary germanate glass systems of GeO2-P2O5-MFx( MFx: CaF2, ZnF2, PbF2, AlF3, and GaF3) are developed to investigate their light scattering properties. Glass-forming regions for these ternary systems are determined, and the systems containing the divalent fluorides, such as CaF2and ZnF2, are found to exhibit wide glass-forming regions. Light scattering (Rayleigh scattering) and related properties for the systems are examined by comparison with those of pure GeO2glass which is prepared by flame hydrolysis techniques. It is clarified that some glasses containing fluorides such as CaF2, ZnF2and GaF3at specified compositions exhibit scattering intensities less than that of GeO2glass. The scattering intensity as low as 0.43 that of GeO2is obtained for the GeO2-P2O5-CaF2system. |
