Abstract An oxyflouroborate glass series of composition 75B 2 O 3 -5Al –(20-x) Li O–xMgF (where x = 0, 5, 10, and 15 mol.%) was prepared using the normal melt-quenching technique. The physical properties (density, molar volume, different optical behaviors) system were investigated via techniques discussed with substitution for MgF . Also, absorption coefficient, both direct indirect energy gaps...

Lithium-based conducting glasses are promising candidates for electrolyte materials of thin-film batteries because they exhibit isotropic ionic conductivity. However, at room temperature most of such conducting glasses exhibit relatively low ionic conductivity values, in the range 10 to 10 S/m. In order to increase the conductivity, some specific additives have been used, one of them being vana...

A major challenge in the modeling of ionically conducting glasses is to understand how large variety possible chemical compositions and specific structural properties influence ionic transport quantities. Here we revisit extend a theoretical approach for alkali borophosphate glasses, where changes conductivity activation energies with borate phosphate mixing ratio are related modifications site...

The sol–gel processing method revolutionizes the biomedical materials field, allowing for customized creation of nano- and porous to help treat toughest challenges in human health. However, this process subsequently produced have mostly been based on silica, particularly terms glasses. Yet, within last two decades, there has increased interest silica-free glass chemistries, such as those borate...

Erbium doped bismuth borosilicate (BBS) glasses, possessing the broadest 1.55 μm near infrared (NIR) emission band among oxide glasses, stand out as excellent fiber material for optical fiber amplifiers. In this work, we demonstrate that both broadened and enhanced NIR emission of Er(3+) can be obtained by sensibly combining the effects such as mixed glass former effect, phonon-assisted energy ...

Bismuth-germanate glasses, which are well known as a promising active medium for broadband near-infrared spectral range fiber lasers and an initial matrix nonlinear optical glass ceramics, have been synthesized in 5–50 mol% Bi2O3 wide concentration range. Their structural physical characteristics were studied by Raman FT-IR spectroscopy, differential scanning calorimetry, X-ray diffraction, opt...
