Polarizability, optical basicity and electric susceptibility of Er 3+ doped silicate borotellurite glasses
TL;DR: In this paper, an erbium doped glass system was fabricated using the chemical composition {[(TeO 2 ] 0.7 (B 2 O 3 ) 0.3 ] 0.8 (SiO 2 ) 0.2 ] with x = 0.05 by melt-quenching method and the glasses were subjected to FTIR and XRD to study the glass structural changes and amorphous nature respectively.

Effect of Bi2O3 on gamma ray shielding and structural properties of borosilicate glasses recycled from high pressure sodium lamp glass
TL;DR: In this paper, the borosilicate glass was recycled from high pressure sodium lamp glass (HPSg) and investigated as a starting material for radiation shielding glass, and the results clearly revealed that mass attenuation coefficient and other parameters depends on concentration of Bi2O3 and addition of Bi 2O3 significantly increased shielding capability of glass samples against gamma rays as well as fast neutrons.
