Summary: A multi-component glass system 65B(2)O(3)-20Bi(2)O(3)-10Al(2)O(3)-(5-x)MgO-xCuO was fabricated using the melt quench mechanism. X-ray diffraction confirmed the amorphous nature of the specimens, while Fourier transform infrared studies revealed bands associated with borate and bismuth groups. The optical band gap of the glasses decreased gradually with an increase in CuO content, and the sample doped with 1 mol% CuO showed the highest conductivity in dielectric studies.

Summary: The structures of glasses in the lithium-bismuth orthoborate composition range show deviation from the short-range order structure of crystalline end-members. The increase in bismuth oxide content leads to an increase in the fraction of tetrahedral boron and a continuous rise in glass transition temperature. However, the glass stability reaches a maximum in the multicomponent glass of x = 40.

Summary: The study investigated the physical, optical, and gamma ray shielding behavior of four Bi2O3-Li2O-P2O5 glasses, showing an increase in glass density and molar volume with bismuth oxide content. The optical band gap energies decreased and the glasses were found to be non-metallic based on M values. Radiation shielding evaluation revealed comparable mass attenuation coefficients but with differences near certain energy levels, with higher values when Li2O oxide is replaced with Bi2O3 oxide, leading to improved radiation attenuation properties.

Summary: The optical and experimental gamma-ray and neutron attenuation properties of tantalum pentoxide reinforced Bi2O3-TeO2-ZnO ternary glasses were investigated. The absorption edge shifted from 380 nm to 390 nm due to translocation of ZnO/Ta2O5. Doping the structure with Ta2O5 led to a decrease in the optical band gap values and an increase in Urbach energies, and the addition of Ta2O5 changed the overall nuclear radiation attenuation properties of the glasses.

Summary: This study investigates the effects of different concentrations of Bi2O3 and Li2O on the physical, structural, optical, and radiation-absorbing properties of glasses. The results show that the addition of Bi2O3 increases the density and molar volume of the glasses, while decreasing the oxygen packing density. Furthermore, the addition of Bi2O3 has different effects on the ability of the glasses to shield gamma rays and fast neutrons. These findings demonstrate the significant potential of this glass for radiation-shielding applications.

Summary: In this study, lithium strontium magnesium bismuth silicate glasses were prepared via melt quenching technique and characterized using XRD and FTIR techniques. The addition of strontium at the expense of magnesium was found to enhance the vitreous formation and increase the density of the glass samples. The glass system showed indirectly allowed transitions and the dielectric parameters were enhanced with increasing MgO content and temperature.

Summary: The melt-quenching method was used to fabricate a complex Mo-doped glass system, and the status of the samples was checked using XRD diffractometer. The results showed that the increase of Mo content led to changes in several properties, such as the reduction of inter-ionic distance, the increase of two-photon absorption coefficient, and the slight increase of ionicity.

Summary: A series of zinc oxide co-doped with Mn2+ and/or Cr3+ were prepared using the citrate sol-gel method, and full photoluminescence analysis revealed characteristic multiline emissions under UV excitation, resulting in a blue light emission. The depth of the blue light emission was dependent on the type and ratio of additions from Mn2+ and/or Cr3+. Samples co-doped with single Mn2+ or Cr3+ showed higher lifetime values compared to those co-doped with a mixture of Mn2+ and Cr3+. The sol-gel technique demonstrated the potential for producing promising photoluminescent materials.
