“…Cerium-containing glasses have stimulated extensive research interest due to their broad applications in radiation dosimetry and optical engineering. [1][2][3][4][5][6] Exhibiting unique separations between the 5d and 4f energy levels of Ce ions, these materials are commonly used for particle detectors and laser activators. In particular, Ce-doped silica has recently been proposed as a candidate absorber for the inertial confinement fusion facilities to protect the transport mirrors from laser back-reflection, which inclines to damage the surfaces and enforce frequent exchanges of optics consequently.…”

Structure and vibrations of cerium in silica glass from molecular dynamics simulations

et al. 2020

Molecular dynamics simulations are performed to investigate the effect of cerium on the structural and vibrational properties of silica glass. At low-concentration levels, the cerium ions tend to generate longer bonds with bridging oxygens than nonbridging ones, the proportion of which is associated with the average bond length varied with cerium coordination. Formed in the presence of cerium, the bond angles exhibit strong dependence on the types of Ce-O bonds that bring about different angular distributions. Despite the discrepancy in the structures between Ce 3+ and Ce 4+ , similar characteristics of vibrations are observed for the two states. In comparison with the glass formers, the vibrations of cerium that contribute primarily to the low-frequency region show a less localized behavior, whereas the acoustic-like and optic-like modes separate at a much smaller frequency.

“…Glasses are particularly alternative matrices to the other standard materials because of their excellent transparency to visible light and absorbing highenergy gamma rays as well as being modifiable with different chemical compositions and preparation methods [8][9][10]. Recently, some glass systems have been experimentally [11][12][13][14][15], theoretically [16][17][18][19][20] and computationally [20][21][22][23][24][25] reported by a number of researchers in order to investigate their ability to different types of nuclear radiation attenuations. Among various glass matrices, tellurite glasses are well-known to be the most attractive owing to easy of fabrication and some superior physical properties [16,17,[26][27][28][29][30] such as high thermal and chemical stability, low-phonon energy, good infrared transmission, high refractive index and dielectric constant, etc.…”

In the present study, the gamma radiation shielding properties of glasses in CdO-WO 3 -TeO 2 ternary systems have been calculated using WinXCom program. The mass attenuation coefficient ( ), half value layer (HVL), effective atomic number (Z eff ) and electron density (N eff ) values for total photon interaction for a wide range of photon energies from 0.015 to 10 MeV have been estimated. The obtained results for the investigated glass systems have been compared in terms of HVL with some standard concrete and different glass samples in order to validate these glasses in point of the radiation shielding. Among the present glasses, G6 glass sample has the best shielding capability against gamma radiation.

This paper presents a study on the structural, morphological and elastic properties of erbium oxide nanoparticles doped bio-silicate borotellurite glass system fabricated using the technique of melt-quenching with chemical compositional formula {[(TeO 2 ) 0.7 (B 2 O 3 ) 0.3 ] 0.8 (SiO 2 ) 0.2 } 1−y (Er 2 O 3 NPs) y where 0.01 ≤ y ≤ 0.05. The objective of the work was to study the some elastic and thermal parameters associated with non-destructive ultrasonic technique, with the aim of utilizing the glasses for erbium doped fiber amplifier application. Various measurements and Characterizations techniques which includes density and molar volume measurements, energy dispersive X-ray fluorescence, X-ray diffraction (XRD), Fourier transform infrared (FTIR), Transmission electron microscopy and Pulse-echo technique were carried out in this study. The density values for the glasses increased from 4.1900 to 4.6003 gcm −3 with the addition of 1-5% of Er 2 O 3 NPs in the glass structure. The increase can be ascribed to increase in the overall molar weight of the glass due to incorporation of heavy Er 3+ ions. The XRD patterns revealed no presence of sharp peaks with the observed broad hump around 2θ = 20-30° indicating the glassy and amorphous nature of the studied glasses. The FTIR spectra showed absorption with peaks around 1362-1385 cm −1 , 1221-1250 cm −1 , 655-689 cm −1 and 602-630 cm −1 wave number ranges, indicating the presences of H 3 BO 3 , SiO 4 , BO 3 , TeO 3 and TeO 4 structural units in the glass system. The microstructural nature observed in the glass morphology showed nanoparticle agglomerations in the glasses. The ultrasonic velocities, elastic moduli, microhardness, Poisson ratio, softening and Debye's temperatures, thermal expansion coefficient as well as other important parameters were calculated from the density and ultrasonic data. The values of the ultrasonic velocities, elastic moduli, Debye's temperature, softening temperature, thermal expansion coefficient and the acoustic impedance increased with increase in the Er 2 O 3 NPs concentration.
