Summary: A new Bi-doped nitridated germanate glass with tunable ultrabroadband NIR emission and high external quantum efficiency is reported. Spectral analysis, NMR, and other studies provide evidence for the mechanism of luminescence enhancement and tunability, and infer the origin of the new emission bands at around 930 nm and 1520 nm.

Summary: Research on ternary Al2O3-P2O5-Bi2O3 glasses revealed that ultrasonic features are influenced by Al2O3, which tends to insert into the phosphate network to form (AlO4) units. This study correlated changes in density and ultrasonic velocities with structural variations represented by FTIR spectra to examine the function of Al2O3 in the glasses' network. The analysis also inferred variations in structure and elastic moduli based on oscillations of different structural units and the substitution of Bi2O3 with Al2O3.

Summary: Erbium-doped heavy metal oxide glasses with low concentrations of erbium oxide were prepared and extensively studied for their structural and optical properties. The luminescence properties of the glasses were found to improve with increasing Er3+ ion content up to 1.5 mol%, before decreasing due to luminescence quenching. The glasses show promise for potential applications in display devices, optical amplifiers, and green lasers.

Summary: Bismuth-germanate glasses were synthesized in a wide concentration range, and their structural and physical characteristics were studied. The main structural units of the glasses were found to be [BiO6] and [GeO4]. The properties of the glasses, such as density, refractive index, spectral and luminescent properties, were strongly influenced by the amount of bismuth active centers. Heat treatment of the glasses resulted in the formation of various crystalline phases.

Summary: By measuring the structural, optical, physical, and ultrasonic properties of Fe-bismuth borate glasses, it is found that these glasses exhibit stable performance against γ irradiation doses up to 60 kGy. The polarizable Bi3+ ions help block the passage of radiation photons, while the presence of Fe2+/Fe3+ enhances the absorption of defect color centers caused by irradiation.

Summary: Fly ash-based geopolymer composites, mixed with wood fiber and sand, have been shown to have comparable properties to ordinary Portland cement but with lower CO2 emissions. The addition of wood fiber was found to decrease the mechanical properties of the composites, suggesting that a limit of 15 wt.% wood fiber may be ideal for construction applications.
