XRD and FTIR structural investigations of erbium-doped bismuth–lead–silver glasses and glass ceramics
Glasses with the xEr2O3 (100− x)[72Bi2O3· 25PbO· 3Ag2O] composition where x= 0–
20mol% were prepared and later thermally treated. The local environments characteristic of
this system were investigated using X-ray diffraction and FTIR spectroscopy. The results
show that the glass or glass ceramic network structure resembles to that of the host matrix,
being composed of [BiO3],[BiO6],[PbO3] and [PbO4] structural units. The addition of Er2O3
stabilizes the host glass or glass ceramic structure. The erbium ions play the role of a …

The local environments characteristic of this system were investigated using X-ray diffraction and FTIR spectroscopy. The results show that the glass or glass ceramic network structure resembles to that of the host matrix, being composed of [BiO3], [BiO6], [PbO3] and [PbO4] structural units. The addition of Er2O3 stabilizes the host glass or glass ceramic structure. The erbium ions play the role of a network modifier in the studied glasses. It was shown that the heat treatment at 650°C leads to the crystallization of the Bi2O3 and PbO1.44 phases.
