Synthesis, physical, optical and structural studies of B2O3-CdO-Al2O3-PbF2 glasses modified with MoO3 ions

摘要

This manuscript deals with the preparation and detailed physical and structural study of B2O3-CdO-Al2O3-PbF2 glasses reinforced with MoO3 ions. With the addition of MoO3, the density and band gap values decreased while the refractive index increased, confirming the transformation of Mo6+ ions to Mo5+ ions and resulting in the generation of NBO's in these glasses. The FTIR spectra revealed the presence of different borate and aluminate units. The FTIR spectra also indicated the conversion of Mo6+ ions to Mo5+ ions. The effect of MoO3 ions on Raman spectra was clearly visible and indicated the conversion of BO4 to BO3 units, increasing NBO's which helped to explain the density variation.
