Light Scattering Properties in Ternary Germanate Glasses

Abstract
Ternary germanate glass systems of GeO2-P2O5-MF x ( MF x : 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 CaF2 and 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 GeO2 glass which is prepared by flame hydrolysis techniques. It is clarified that some glasses containing fluorides such as CaF2, ZnF2 and GaF3 at specified compositions exhibit scattering intensities less than that of GeO2 glass. The scattering intensity as low as 0.43 that of GeO2 is obtained for the GeO2-P2O5-CaF2 system.
