Abstract Borate glass samples containing chromium and erbium were prepared. According to the density molar volume, Cr 2 O 3 -free sample had an expanded structure. has three distinct absorption bands, according measured optical characteristics, a band was observed at 688 nm due 4 A 2g (F) → E g (G) transition, indicating presence of 6+ . 3+ in bands 446 620 nm, which attributed T 1g (F). Using ...

Abstract Herein, this study introduced a novel strategy for hazardous cement bypass dust (CBD) removal via incorporated it into glassy system having the chemical formula 10Li 2 O–10Bi O 3 –(80 ? x)B –xCBD, where x = 0, 10, 20 and 30%. The doped glass samples with CBD were used as radiation shielding material. structural, optical nuclear properties of CBD-lithium bismuth borate (LBB) investigate...

Near infrared broadband emission characteristics of bismuth-doped aluminophosphate glass have been investigated. Broad infrared emissions peaking at 1210nm, 1173nm and 1300nm were observed when the glass was pumped by 405nm laser diode (LD), 514nm Ar+ laser and 808nm LD, respectively. The full widths at half maximum (FWHMs) are 235nm, 207nm and 300nm for the emissions at 1210nm, 1173nm and 1300...

Radiation shielding is crucial in many types of medical, industrial, and nuclear facilities due to the widespread usage radioactive isotopes. In this research, we examine impact tellurite 65TeO 2 –(35-x)V O 5 -xSm 3 glasses, where x ranges from 0.1 mol%, for its security radiation versus gamma attenuation capabilities. For gamma, effect that systematic replacement Sm with V has on qualities was...

A series of binary tellurite based glasses (Bi(2)O(3))(x) (TeO(2))(100-) (x) was prepared by melt quenching method. The density, molar volume and refractive index increase when bismuth ions Bi(3+) increase, this is due to the increased polarization of the ions Bi(3+) and the enhanced formation of non-bridging oxygen (NBO). The Fourier transform infrared spectroscopy (FTIR) results show the bond...

Niobium doped silver lead borate glasses with the chemical composition (29-x) PbO-yAg2O70B2O3-xNb2O5 (where x= 0.1 to 0.5mol%, y= 1 to 5 mol %) have prepared by conventional melt quenching method.SEM/XRD technique confines glassy nature of the prepared samples. IR and UV optical absorption technique have been used to obtain the information concerning network structure. From the absorption edge ...

New oxychloride lead borate glasses in the xPbCl2–(50-0.5x)PbO–(50-0.5x)B2O3 system were synthesized with a maximum chloride content of 40 mol%. The characteristic temperatures and mechanical optical properties studied. incorporation led to significant expansion transparency range UV (up 355 nm) IR regions 4710 nm). Decreases Vickers hardness, density, glass transition temperature consequences ...
