Summary: The physical, structural, and luminescence properties of lithium aluminum borate glasses were studied with varying concentrations of Gd2O3 and Eu2O3. The glasses composition of interest was successfully synthesized and analyzed using X-ray induced luminescence and photoluminescence. It was found that the emission intensity increased with an increase in Eu2O3 concentration up to 3.0 mol%, and the maximum intensity peak was observed at 614 nm. Decay profile measurements confirmed the occurrence of maximum energy transfer efficiency.

Summary: Inorganic pyrophosphate anions (PPi) play a crucial role in biological processes and serve as important indicators for physiological function evaluation and disease diagnosis. However, there is a lack of straightforward and robust approaches for PPi detection. In this study, an on-off-on fluorescent switching nanoprobe utilizing Fe3+-mediated fluorescent sulfur quantum dots (SQDs) is designed for highly robust PPi detection. The SQDs, capped with bovine serum protein (BSA), exhibit good water dispersibility and optical stability. The presence of Fe3+ induces aggregation of the SQDs, leading to fluorescence quenching. PPi selectively binds with Fe3+, preventing SQD aggregation and resulting in fluorescence recovery. The designed nanoswitch shows great potential for the future development of quantum dot-based biosensors for analyte detection.

Summary: This study investigated the effects of different doses of gamma irradiation on the structural, thermal, photoluminescence, and optical properties of PVA/Gd2O3 nanocomposite films. It was found that gamma irradiation significantly influenced the thermal stability of the films, as well as the energy gap and Urbach's energy. The results suggest that irradiated PVA/Gd2O3 nanocomposite films are promising materials for flexible optoelectronic devices.

Summary: This study systematically investigated the effect of Ag nanowires (NWs) on the optical properties of optoelectronic polymer poly[2-methoxy-5-(2ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV). The decoration of Ag NWs with an average diameter of 160 nm leads to improved absorption and photoluminescence ability due to the coexistence of localized surface plasmons and propagating surface plasmons. The results showed significant enhancement, with 180% improvement in absorption and 190% improvement in photoluminescence at around 630 nm. Furthermore, the Ag NWs were found to effectively suppress non radiative recombination and enhance radiative recombination.

Summary: This study introduces an electrophoretic process to concentrate boron nitride nanosheets onto a designated electrode surface, forming a seamless bilayer structure with significant modulus difference, called the unimorph nanocomposite dielectric elastomer (UNDE). This material shows improved performance in terms of breakdown field strength and durability compared to conventional nanocomposite dielectric elastomers. Multiple UNDE units can be formed using a simple electrophoretic concentration process, and they can be used to create high-stroke actuators. The experimental disc-shaped actuator demonstrated the capability of a high-speed lens motor to vary the focal length of a two-lens system by 40 times.

The concept of heterostructured detectors has been proposed to bypass the current performance limitations. Based on Monte Carlo simulations, a survey of heterostructure performance versus detector design is presented, enabling the establishment of design rules for the development of improved detectors.

Summary: Cesium lead bromide quantum dot (CsPbBr3 QD) has great potential as a luminescent material for gamma ray detection. However, its self-absorption reduces the scintillation light yield. By co-dissolving a fluorescent dye PM-580 in the solution, the self-absorption of QDs can be overcome, and the scintillation decay kinetics can be accelerated. The liquid scintillator loaded with 40 wt % CsPbBr3 QD showed excellent performance in terms of light yield and energy resolution.

Summary: Advancements in electronics to interact with tissue require overcoming material constraints. We propose a layered architectural composite design that eliminates strain effects on device performance by coupling strain-induced cracked films with a strain-isolated conductive pathway, resulting in stretchable, highly conductive, and strain-insensitive bioelectrodes. These bioelectrodes can be used for in vivo biomarker sensing and neuromodulation.

Summary: By measuring the low-temperature photovoltaic properties, photoluminescence spectra, and current-voltage characteristics, it is discovered that a major difference exists between halide perovskites and polymer light-emitting electrochemical cells. In perovskites, ion migration is accompanied by doping, while in polymer light-emitting electrochemical cells, ion migration leads to doping only when the bias exceeds the bandgap/e of the conjugated polymer.
