The effect of MoO3 substitution for B2O3 on the structural and optical properties of bismuth borate glass

Fifty Bi2O3-(50-x) B2O3-xMoO(3) glasses with x = 0, 5, 10, 15, and 20 are made using the melt-quenching procedure (mol%). The structural and physical properties of the produced glass samples were investigated using X-ray diffraction (XRD), infrared (FTIR), and optical absorption (UV/Vis/NIR) spectroscopy. In vitreous compositions including MoO3 up to 15 mol% and semi-crystallized samples containing 20 mol%, the environment of cations was examined. When the sample is poured into the air, the Bi2MoO6 crystalline phase forms, and the crystalline intensity increases. The isolated MoO4 presence in structural groups in the glass network can be seen in FTIR data. The thermal stability of glass samples containing 5 and 10 mol% MoO3 is higher than that of other samples.

Automated summary

Fifty Bi2O3-(50-x) B2O3-xMoO(3) glasses with different mol% were prepared by the melt-quenching method. The structural and physical properties of the glasses were investigated using XRD, FTIR, and UV/Vis/NIR spectroscopy. The presence of Bi2MoO6 crystalline phase was observed at certain MoO3 concentrations. The glass samples containing 5 and 10 mol% MoO3 exhibited higher thermal stability.
