Summary: This study focuses on the optical properties of Au-Ag bimetallic nanoparticles doped in dichroic glasses, highlighting the importance of precursor materials (AgNO3, AgCl, and AgI). The incorporation of silver and gold in the glass matrix reduces nanoparticle size and enhances the nonlinear refractive index, with potential overlap of surface plasmon resonance of Ag and Au. Differences in bandgap energy due to different dopants impact the nonlinear optical properties of the nanoparticles.

Summary: The present article explores the structural, morphological, and optoelectronic properties of Silver (Ag) doped Lead sulfide (PbS) nanoparticles. X-ray diffraction and scanning electron microscopy were used to examine the structural and morphological properties of the nanoparticles. The doping of Ag into the PbS lattice and the increase in electrical properties of Ag-doped PbS nanoparticles were confirmed. The optical band gaps and Urbach energies of the nanoparticles were also determined.

Summary: In this study, sequential implantation of gold and silver ions with varying ion fluence, as well as subsequent annealing, were used to modify the optical and plasmonic properties of TiN thin films and correlate them with their structural properties. The implanted films showed reduced metallicity and lower losses compared to the as-deposited film, while subsequent annealing partially recovered the destroyed structure and improved the metallic properties. By optimizing the implantation fluence of silver ions, TiN films with desirable optical performances were obtained.

Summary: When partial discharge faults occur in SF6 gas-insulated equipment, it leads to reduced insulation performance due to the production of various decomposition products. Monitoring the concentration of typical SF6 decomposition products allows for the early diagnosis of insulation faults in gas-insulated equipment. GaNNT doped with metal, such as Au, Ag, and Cu, shows improved gas-sensitive properties and can be used as a potential gas-sensitive material. Density functional theory (DFT) calculations are used to compare the gas-sensitive response characteristics of metal-doped GaNNT to SF6 decomposition gases. The results show that Ag-GaNNT has the highest gas-sensitive abilities and selectivity for SO2F2 gas.

Summary: In this study, mesoporous and macroporous nanosheets of Ag.Co3O4 were successfully synthesized with high catalytic activity for efficient removal of toxic dyes under natural sunlight. The exceptional activity of Ag.Co3O4 sample is attributed to its novel bimodal porous structure, high surface area, narrow bandgap, good electrical conductivity, and low charge transfer resistance, showing great potential for eliminating harmful dyes from industrial effluents.

Summary: Terbium doping enhances the photodetection properties of Ag/CdS/Ag devices, improving sensitivity, responsivity, detectivity, and response time compared to pure CdS devices. The change in conduction mechanism from Schottky to ohmic is responsible for the enhanced performance.

Summary: Transparent microelectrodes have been widely studied in the biomedical field due to their advantages in simultaneous electrical and optical interrogation of cell/tissue activity. In this study, a microelectrode array (MEA) with gold-coated silver nanowires (Au-Ag NWs) was designed to achieve desirable mechanical stretchability, optical transparency, electrochemical performance, and chemical stability. The MEAs exhibited high optical transparency, low electrochemical impedance, stable chemical and electromechanical performance, and superior capability for colocalized electrophysiological and optical mapping of cardiac function.

Summary: Sb-doped S-Ga2O3 crystals were grown using the OFZ method, and they showed high quality according to X-ray diffraction and rocking curves. Raman spectra indicated Sb substitutions in the octahedral lattice. The carrier concentration, electronic mobility, and electrical resistivity of Sb-doped crystals varied with increasing Sb doping concentration. The S-Ga2O3 crystals had good transmittance in the visible region, but decreased in the infrared region due to the increased carrier concentration. Transmittance in the UV region was high, with a cutoff edge at 258 nm.

Summary: In this study, we investigated the in-plane thermal conductivity of surface plasmon polaritons (SPPs) propagating along thin metal films. Numerical simulations and experiments showed that considering the size effect of the permittivity of thin metal films reduces the plasmon thermal conductivity by approximately 30% and increases the film thickness at which maximum thermal conductivity occurs.

Summary: This study focuses on sol-gel derived SnO2-TiO2 thin films deposited on silicon wafer type Si (100) substrate using spin coating technique, followed by heat treatments at four different temperatures. XRD characterization reveals the formation of nano-crystalline phase at 400 degrees C and further crystallization with increasing annealing temperature. Optical and dielectric properties analysis demonstrates universal many body response over a broad frequency range, presenting variations in structure and performance of the films.
