摘要

Abstract In this work, the role of insertion cobalt(II) on the physical properties, dielectric spectroscopy, and photon attenuation parameters of the prepared glasses 25NaF-10ZnO-(65-x)B2O3-xCoO-0.6Y2O3: x = 0.0 (Co-0.0) ≤ x ≤ 0.5 (Co-0.5) mol% has been investigated. The amorphous state of samples verified via the XRD measurements. The density (ρ) ∈ [2.9824, 3.0058 g.cm−3]. The molar volume (Vm) ∈ [21.868, 21.715 cm3.mol−1] as an increase of CoO from 0.0 to 0.5 mol% in the glass network. Dielectric spectroscopy of borate glass loaded with varying cobalt content was investigated throughout frequency range from 50 to 5 MHz. The recorded dielectric constant at 3 kHz was enhanced from 14.4 to 17.8 by cobalt doping. The dependency of tangent loss (tan δ) for all investigated glasses on frequency is normal behavior with dielectric relaxation which is enhanced and shifted by cobalt doping. At the photon energy (E = 0.015 MeV), the mass-attenuation-coefficient (MAC) values were 10.192, 10.246, 10.300, 10.354, and 10.408 cm2/g for the samples Co-0.0, Co-0.1, Co-0.2, Co-0.30, Co-0.4, and Co-0.5, respectively. These MAC values are corresponding to as increment of 0.216 cm2/g between the low and high CoO contents presented in the glass samples. Values of half value layer (HVL) of all proposed specimens were more significant than that of RS-360 and RS-520 commercial glasses. Results confirmed that the suggested glasses are suitable for radiation attenuation.
