Synthesis and characterization of cadmium doped lead�?�borate glasses

[摘要] Cadmium doped leadâ€�?�borate glasses were prepared from the melts in appropriate proportions of PbO₂, H₃BO₃ and (15â€�??40 mol%) CdO mixture in the temperature range 700â€�??950°C. The infrared spectra of the glasses in the range 400â€�??4000 cm^-1 show their structures. No boroxol ring formation was observed in the structure of these glasses. Furthermore, doped cadmium atoms were not seen in tetrahedral coordination. But the conversion of three-fold to four-fold coordination of boron atoms in the structure of glasses was observed.
