Summary: The Li2B4O7:Cu,Eu glass doped with 1.0 mol.% CuO and Eu2O3 impurities was investigated using XRD, EPR, optical absorption, and photoluminescence techniques. The local structure parameters were determined by analyzing XRD data. The results reveal the incorporation of Cu2+ and Cu+ ions in the Li2B4O7 glass, as evidenced by EPR and optical absorption spectroscopy. The optical properties, such as optical absorption spectrum, band gap, and Urbach energy, were also studied. The photoluminescence analysis showed the presence of broad blue emission from Cu+ ions and narrow emission bands from Eu3+ ions.

Summary: In this work, CuO-doped MgO-Al2O3-SiO2 based glasses were successfully synthesized using conventional melt quenching method, and the influence of CuO content on the structure and properties of the glasses was investigated. The results showed that CuO acted as a glass modifier to depolymerize the silicate network, with the main crystalline phase being alpha-cordierite. The presence of Cu2+ ions in the octahedral sites was confirmed by the characteristic absorption band around 750 nm on the optical transmittance spectra, and luminescence caused by Cu+ ions resulted in a decrease in luminescence lifetime.

Summary: Understanding the mechanisms contributing to dielectric properties of glasses is critical for designing new compositions for microwave frequency applications. In this work, dielectric permittivity was measured for a series of niobiosilicate glasses with varying compositions. The calculations of polarizability and experimental results reveal that SiO2 polarizability depends on the chemistry and connectivity of the glass, which has important implications for designing glass compositions for microwave frequency applications.

Summary: Antimonene oxide quantum dots were prepared using liquid-phase antimony exfoliation and sol-gel methods, showing good compatibility and high dispersibility in both liquid and solid media. The hybrid ormosil gel glasses, with concentrations of dopant quantum dots as high as 2.00 wt%, exhibited outstanding optical limiting performance in the visible, mid-wave, and near-infrared regions. The mechanism of optical limiting included nonlinear absorption, nonlinear refraction, and nonlinear scattering, which could have promising applications in fields such as laser protection and laser shaping.

Summary: In this study, the temperature-dependent Urbach energy in lead halide perovskites containing different numbers of cation components was investigated using photocurrent spectroscopy. The results showed that the Urbach energies at room temperature were 13.0 +/- 1.0 meV, 13.2 +/- 1.0 meV, and 13.5 +/- 1.0 meV for single, double, and triple cation perovskite, respectively. The dominant static disorder in perovskites was found to be derived from zero-point phonon energy rather than structural disorder.

Summary: In this study, the dielectric properties and dielectric breakdown strength (DBS) of PbO-B2O3-SeO2:Ho2O3 (PBSH) glass ceramics were investigated as a function of Au2O3 content. It was found that an increase in Au2O3 content resulted in an increase in structural imperfections, leading to an increase in space charge polarization and dielectric constant. Furthermore, the increase in Au2O3 content was also found to enhance the polaronic exchange between two structural groups of SeO2, resulting in an increase in ac conductivity.

Summary: Li2O-HfO2-SiO2-Tm2O3:Au2O3 glass samples with fixed Tm2O3 content and varying Au2O3 concentration were prepared and characterized. The influence of Au-0 metallic particles on the blue emission of Tm3+ ions was investigated. Optical absorption spectra revealed multiple bands excited from the H-3(6) level of Tm3+ ions, and a broad peak in the 500-600 nm range due to surface plasmon resonance of Au-0 metallic particles. Photoluminescence spectra of Tm3+ and Au2O3 co-doped glasses showed intense blue emission, which increased with higher Au2O3 content. The enhancement of blue emission by Au-0 metallic particles was discussed in detail using kinetic rate equations.
