Pr2O3 doped bismuth-phosphate glasses have been produced via an ordinary melt quenching tool. Glasses have a chemical content (5–x) Al2O3–15Na2O–20Bi2O3–60 P2O5 –xPr2O3 with x values between 0 and 2 mol%. The structural and mechanical features of the prepared phosphate-based glasses were investigated. The XRD spectra confined the amorphous type of these glasses. Furthermore, the influence of Pr2O3 on the mechanical features has been explored and related to the structure. The relationship between structural variations and the contents of Pr2O3 has been investigated in terms of FTIR and by the determination of the density and the ultrasonic velocity. The density and the ultrasonic velocities were utilized to calculate the elastic moduli of the glasses. The acquired results indicate that the ultrasonic velocity and the elastic moduli increase as a function of Pr2O3 in the whole explored studied glasses. The analysis of FTIR spectra refers that Pr2O3 is interstitial settled in the phosphate network with [PrO7] associated with covalent Pr–O–P bonds, whereas Bi2O3 and Al2O3 settle on the network with [BiO6], and [AlO6] units. These experimental features coincide with a compact structure and act in a manner that Pr2O3 incorporates the glassy network with plenty of bridging oxygen atoms. These arguments encourage the use of these glasses in radiation shielding materials.

“…Furthermore, the inspections of the elastic features of glasses as a function of composition are of great significance, due to the abundant information about the network of these glasses. Recently, there are an inclusive number of works on the elastic features of phosphate glasses, by utilizing ultrasonic measurements [17][18][19][20][21].…”

“…[36,37] The band observed at 585 cm À1 may be attributed to the vibration of the TeO 4 trigonal bipyramid group. [38] The peak around at 762 cm À1 corresponds to the symmetric stretching vibration of P-O-P bonds (PO 2 ) of Q 1 tetrahedra along with NBOs atom. The band position at $943 cm À1 was attributed to the asymmetric stretching vibration of P-O-P bonds (PO 2 ) of Q 2 tetrahedra.…”

Telluro zinc phosphate (TZP) glasses doped with different concentrations of Eu 3+ ions were prepared and their physical, structural, and luminescence properties were studied in detail to reveal the utility of the as-prepared glass for white light-emitting diode (w-LED) applications. The broad hump in the diffraction pattern specified the amorphous behaviour of the TZP glass. The various vibrational shoulder linkages were characterized using the Fourier transform infrared (FT-IR) spectroscopy. The

“…The increasing use of radionuclides in nuclear reactors to obtain energy, as well as in treatment and medical imaging, and in laboratories for scientific research, requires more scientific studies to find suitable shields for gamma rays that are highly efficient in attenuating gamma rays and appropriate to transparency and thickness. The use of glass inlaid with heavy materials, such as bismuth and lead, can lead to a decrease in the thickness of the shielding material and reduce the level of gamma rays to a safe level, and the transparent glass material is better than other materials for shielding, such as conventional concrete used in nuclear reactors [1][2][3].…”

Glass samples were synthesized according to 10Li2O + 20CuO + xBi2O3 + (70 − x)B2O3, where x = 0, 10, 20, 30, 40 mol% by the melt-quenching method. The ability of the prepared glass to protect against gamma rays and neutrons was examined experimentally and theoretically. The mass attenuation coefficient (MAC) was calculated experimentally at energies of 0.662, 1.173, and 1.333 MeV using 137Cs and 60Co sources. The obtained results were compared with the theoretical ones using a Phy-x/PSD software program version 0.1.0.0. It was found that the experimental and theoretical results are very agreed upon. Moreover, other nuclear radiation shielding parameters were evaluated. The results showed that the addition of bismuth oxide leads to an improvement in the ability of the composite glass to attenuate gamma rays by increasing the values of MAC and Zeff, while it led to a decrease in the HVL and MFP, as well as the EBF and EABF. The results also showed that the addition of copper oxide led to an improvement in the ability of the present glass to slow down fast neutrons. Sample BiS40 showed the best result for gamma ray attenuation and sample BiS10 gave the best result for fast neutron removal cross section. The results were compared with some materials used for gamma ray shielding and fast neutron removal cross section, and it was concluded that samples Bi40 and BiS10 outperformed all commercial materials.
