- Abstract
Structural, optical, and gamma radiation safety properties of 46V2O5·46P2O5·(8–x)B2O3·xZnO (x = 0,2,4,6, and 8 mol%) abbreviated as VPB/Zn glasses were investigated. The structure of the synthesized glasses has been examined via FTIR spectra within the range of 400–1500 cm−1 at room temperature. UV–Vis–NIR measurements of the proposed glasses were performed within the range of 200–3300 nm. The optical characteristics such as optical energy bandgap ( E Optical ), refractive index (nLinear), and Urbach's energy (EU) have been determined. In addition, the mass attenuation coefficients (MAC) for VPB/Zn glasses were performed utilizing MCNP-5 simulation code and XCOM program for various gamma ray energy varied in range 0.015–15 MeV. Based on MAC values, the equivalent atomic number (Zeq) and buildup factors (EABF and EBF) were evaluated. Results reveal that the direct E Optical Tauc ′ s of the VPB/Zn glasses ranged from 0.688 to 0.710 eV, while from 0.560 to 0.647 eV for the indirect transition. The admission of the ZnO improves the MAC of the VPB/Zn glasses. Thus, one can conclude that the proposed glasses can be applied for optical devices as semiconductor glasses and considered as good materials for γ-rays shielding.
