Abstrakt: Novel platinum-doped borate glass systems with chemical formula 25ZnO-25BaO-xPtO2-(50-x)B2O3: (0 ≤ x ≤ 1) mol%) have been prepared via the traditional technique of melt-quenching. The significant influence of PtO2 on the physical, linear/nonlinear optical properties, and γ-rays attenuation competence of the prepared Pt0.0–Pt1.0 glasses were examined. XRD measurements confirmed that the proposed glasses were in amorphous nature. The density (ρglass) of Pt samples enhanced from 3.05 ± 0.01 to 4.10 ± 0.01 g/cm3 for Pt0.0 and Pt1.0 glasses,. Values of optical energy band (Eg) were varied from 2.921 to 1.551 eV for Pt0.0 to Pt1.0 glass samples. The linear (no) and nonlinear refractive indices (n2) were changed from 2.423 to 2.898 and 5.962 × 10–11 (esu) to 26.528 × 10–11 (esu), respectively. At low photon energy (0.015 MeV), the mass attenuation coefficient (MAC) possessed maximum values ranged between 38.182 and 40.783 cm2/g for Pt0.0 and Pt1.0 glasses, respectively. The half-value layer (HVL) parameter followed the order (HVL)Pt0.0 > (HVL)Pt0.1 > (HVL)Pt0.2 > (HVL)Pt0.3 > (HVL)Pt0.4 > (HVL)Pt0.5 > (HVL)Pt0.75 > (HVL)Pt1.0. Our results depicted that Pt glasses can be used as a preferable alternative material for radiation safety application. [ABSTRACT FROM AUTHOR]
