Abstract

Three glass systems of Cu2+ ions doped lithium-borate with the composition of 56B2O3 + 25Li2O + 10Na2O + 5CaO + 2SrO + 2Al2O3 + 0.5TeO2 + xCuO, where x = 0.0, 0.2, and 0.3 wt% are synthesized by the conventional melt quenching method. X-ray diffraction (XRD) studies, Fourier transform infrared (FTIR) spectroscopy, electron spin resonance (ESR) spectroscopy, physical properties and ionizing radiation shielding performance of the prepared Cu2+-glasses have been investigated. All prepared Cu2+-glasses are in an amorphous structure nature. The density increases from 2.4379 to 2.4597 g.cm−3 as the Cu2+ ions content increased from 0.0 to 0.3 wt%. The FTIR spectra reveal four basic active areas in the IR spectra region (400–4000 cm−1). FTIR absorption spectra of glasses after irradiation with 10 kGy show that some of BO3 triangles are converted into BO4 groups. The ESR spectra for the investigated glasses exhibit highest intensity of the signal at the highest irradiation dose of 10 kGy. Linear attenuations coefficients (LACs) of the investigated glasses were arranged in order: (Cu0.0)LAC < (Cu0.2)LAC < (Cu0.3)LAC. Half-value layers (HVLs) values were found 0.088, 0.085, 0.083 cm, and 15.54, 15.43, 15.32 cm for Cu0.0, Cu0.2, and Cu0.3 at 0.015 and 15 MeV, respectively. MFPs arranged from 0.128 to 22.419 cm, and from 0.12 to 22.119 cm for Cu0.0–Cu0.3 at 0.015 and 15 MeV, respectively.
