| Abstract: | A number of
samples of silver phosphate glasses doped with 1%, 5%, 10% and 20% zinc
and cadmium halides were prepared. Control samples of undoped silver phosphate
glasses were also prepared. These glasses were characterized by
X-ray diffraction, IR spectra, ion transport, and DSC studies. The Tg values obtained from DSC
curves were found to increase with increasing concentration of the dopants
(Zn/CdX2) where X= Cl, Br, I in all the cases. The Tg and the conductivity
values of all the samples of silver phosphate glasses show the following trend:
Tg (CdX2)
> Tg (ZnX2);
X = Cl or Br or I; Tg
( MCl2 ) > Tg
(MBr2) > Tg
(MI2); M = Cd or Zn; σ (MI2) > σ (MBr2) > σ (MCl2); M = Cd or Zn. These results have
been discussed and explained on the basis of changes in the structure of the
glass matrix by the addition of the halide ions of different sizes, IR spectra
and ion transport studies. |
