摘要

A glass material doped with Nb3+ ions, composed of 30B2O3, 39P2O5, 10LiCO3, 5SrO, 5AgO, 5Al2O3, 5ZnO, and 1Nb2O3, was developed using the melt-quenching approach. Structural analysis was conducted through Powder X-ray diffraction (P-XRD), to confirm the glass amorphous nature. The Fourier-transform infrared (FTIR) and FT-Raman spectroscopy were employed to rectify the nature of chemical bonding as well as the presence of functional groups in the glass matrix. Optical studies included the refractive index measurements and optical properties to characterize the material’s interaction with UV–Vis light. The Obtained bandgap energy is 3.5 eV and refractive index found to be 1.48. Photoluminescence properties of the Nb3+ ions were explored to evaluate their emission potential. The glass exhibits a reddish-orange emission. The surface morphology was examined using Scanning Electron Microscopy (SEM), while the elemental composition was determined through Energy Dispersive X-ray Spectroscopy (EDS). Gamma-ray shielding parameters, such as the effective atomic number (Zeff), mass attenuation coefficient (MAC), half-value layer (HVL), and mean free path (MFP), were evaluated using computational tools. These findings prove that the prepared glass has the potential to be used as a material requiring effective radiation shielding applications.
