Summary: In this work, a unique class of double-tungstate phosphors is reported that exhibit near-unity quantum yield of Tb3+ and Eu3+ emissions. The activator ions can be isolated to confine absorbed photon energy, resulting in high quenching concentration. The thermal enhancement of Tb(3+) emissions is achieved through interionic cross-relaxation, providing excellent thermal sensitivity and resolution for single-band ratiometric thermometry.

Summary: Carbon dots (CDs) are promising luminescent materials for optoelectronic applications due to their low cost, eco-friendliness, and color-tunable photoluminescence (PL). However, the research on solid-state emissive CDs is limited by aggregation-caused quenching (ACQ) and poor film-formation ability. In this study, CDs functionalized with branched-polyethylenimine (b-PEI) were synthesized to overcome the ACQ effect and exhibit efficient red and NIR emission in an aggregate state. The designed CDs also demonstrated good film-formation ability, which enhances their value for film-based optoelectronic devices.

Summary: There is significant interest in trivalent chromium ion-doped phosphors for near-infrared luminescence. In this study, trivalent chromium-doped SrGa2Si2O8 phosphors emitting near-infrared light were synthesized. The electronic structure was calculated and a transformation from [GaO4] tetrahedron to [CrO6] octahedron was observed due to the doping of Cr3+. The luminescent properties of SrGa2Si2O8:Cr3+ were systematically studied, and its high thermal stability and potential as a near-infrared LED light source were demonstrated.

Summary: Bismuth (Bi) doped glasses and fibers have gained attention for their broad and long lived near infrared (NIR) emission. Codoping rare earth ions is a feasible way to modulate the NIR emission properties of Bi, but limited success have been achieved. By investigating nonactive rare earth (RE) codoped aluminoborate glasses, it is found that the addition of nonactive RE ions changes the glass structure and optical basicity, altering the optical properties of Bi.

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.
