Abstract

Abstract: A series of borotellurite glass system doped with copper oxide was synthesized using the method of melt quenching. The density of the glass decreases whereas its molar volume increases in respect to copper oxide concentration. The amorphous nature of prepared glasses was proven with the utilisation of XRD spectra. Meanwhile, the glass samples' elastic properties are determined from the measurement of longitudinal and shear velocities using ultrasonic technique. The longitudinal modulus, shear modulus, bulk modulus and Young's modulus has shown an irregular trend that fluctuates within certain limits. Moreover, the FLUKA Monte Carlo code is implemented to determine the shielding features at gamma energy of 0.3565, 0.6616, 0.8348 and 1.3325 MeV. Linear attenuation coefficients acquired from FLUKA and XCOM are found to be in good agreement with relative difference <1%. The glass sample B2 O3 TeO2 CuO1 (with highest percentage of TeO2 ) is found to be the best shielding glass material in this study. Highlights: The melt-quenching method was used in the fabrication of glass. X-ray diffraction spectra confirmed that all glass samples are amorphous in nature. Radiation shielding features of B2 O3 TeO2 CuO glass system are for useful gamma-ray energies. The B2 O3 TeO2 CuO (highest percentage of TeO2 ) is found to be the best shielding glass composition.
