Summary: Co-doped borotellurite (BTZN) glasses with Ce3+ (0.5 mol%) and varying concentrations of Sm3+ (0.5, 1.0, 1.5 and 2.0 mol%) were successfully synthesized using the melt quenching method. X-ray diffraction and SEM images confirmed the amorphous nature and homogeneity of the glass samples. The effective energy transfer (ET) from Ce3+ to Sm3+ was observed, leading to improved luminescence properties of Sm3+. The luminescence lifetime of BTZN:Ce/Sm glasses decreased with increasing Sm3+ concentration, indicating enhanced ET efficiency through dipole-quadrupole interaction. The CIE coordinates of the glasses could be adjusted from blue to bluish-white colors by varying the Sm3+ concentration.

Summary: We synthesized Sm-doped Gd2O3-modified borate glasses that emit orange light and investigated their structure modification, energy transfer, emission dependence on concentration, scintillation efficiency, and laser performance. These glasses are suitable for near UV excitation lasers due to their strong near ultraviolet absorption. By using the Judd-Ofelt theory and spectral characteristics, we determined the oscillator strength, stimulated emission cross-section, radiation transition probability, and branch ratios. We also examined the UV-sensitized Sm3+ lifetime and photoluminescence spectra and found that the energy transfer between Gd and Sm and from Sm to luminescence centers is responsible for the UV to visible/orange emission achieved at different excitation wavelengths.

Summary: Fluoroborosilicate glasses with different CeF3 concentrations were studied to examine their scintillation properties. The density and refractive index of the glasses increased with increasing CeF3 concentration. The luminescence characteristics of Ce3+ in the glasses were investigated, and an intensity peak at 345 nm was observed. The concentration quenching of Ce3+ emission was attributed to energy transfer between Ce3+-Ce3+ ions. The decay curves of the glasses could be fitted by a double exponential function.

Summary: The novelty of this research lies in the preparation of phosphate glasses doped with 1 mol% Eu2O3 and incorporating 10 mol% CaO or CaF2, focusing on their structural and optical features, as well as their influence on scintillation spectral response. Replacing CaO (OE glass) with CaF2 (FE glass) leads to changes in density, molar volume, and O-H group bands in the IR spectral range. The optical absorption of the glasses shows various peaks in the UV-Visible and NIR ranges, and the phonon energies are consistent with the excitation spectra of Eu3+ ions. The emission spectra reveal the surrounding environment of Eu3+ ions and the highest red-emitting transition under UV light and X-ray radiations.

Summary: The dielectric properties of multi-component silicate oxide glasses were studied, focusing on high dielectric constant oxyfluorosilicate (OFS) glasses. Infrared reflection spectroscopy and terahertz (THz) timedomain spectroscopy were used to investigate the vibrational parameters and ionic pairs in OFS glasses. The THz dielectric strength of OFS glasses was found to be dominated by the lowest frequency mode, while the high frequency dielectric constant showed a superlinear dependence on the electronic polarizability of oxygens. The low frequency mode contribution to the dielectric constant was enhanced by the ionicity and exhibited a steeper dependence on the electronic polarizability.

Summary: Borotellurite (ZnBiBaBFTe: ZnO + Bi2O3 + BaF2 + B2O3 + TeO2) glasses were fabricated by varying Tb2O3 concentration via the conventional melt and rapid quenching process. The glass stability (150 degrees C) and thermal stress (0.336) were evaluated using the differential thermal analysis. The rising value in the molar volume (39.69-43.86 cm3/mol) and field strengths (6.69-19.41 x 1015 cm- 2) was due to the decrease in the density (2.932-2.804 gm/cm3) and inter-atomic distances (5.25 -3.08 angstrom) of Tb3+ ions in ZnBiBaBFTe glasses.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
