Summary: In this study, it was found that the symmetry of 2D arrays of gold nanoparticles significantly impacts the sensitivity to refractive index changes. Utilizing asymmetric nanoparticle layouts can enhance sensitivity, and further reducing symmetry can improve sensor performance. By changing the polarization of incident light, such asymmetric nanostructures can function as sensors based on SERS and LSPR plasmon.

Summary: Coupled plasmonic systems are of interest for their optical properties and potential applications. An improved method for mapping geometric configurations to optical properties accurately is developed, allowing for the realization of low-loss cavity and interesting effects in metallic nanoparticles. Asymmetric coupling is predicted to lead to chirality and directional energy transfer in hybrid plasmonic systems.

Summary: In this study, a HCl-doped copolymer of ortho phenylene diamine and meta phenylene diamine was prepared, and microporous structure thin films of hybrid copolymer/ZrO2 nanocomposite were fabricated. The addition of zirconium oxide nanoparticles improved the crystallinity and optical properties of the copolymer. Molecular structure optimization and frequency calculations were performed using computational models, showing good agreement with experimental data. The findings suggest the potential use of hybrid nanocomposite films in polymer solar cell applications.

Summary: PVA/Ag nanocomposite with different concentrations of silver nanoparticles (Ag NPs) was successfully synthesized using the solution casting method. The effect of Ag NPs concentration and UV irradiation on the optical and structural properties of the nanocomposites was investigated. It was found that the absorption intensity increased and the optical band gap decreased with the increase in Ag NPs concentration and UV exposure time.

Summary: This work investigates the radiation shielding properties of PVA films containing BaTiO3 nanoparticles, with experimental measurements and comparison to simulation results. The optical properties and shielding efficiency of the films were found to change significantly as the BaTiO3 content increased. The study demonstrates a strong agreement between experimental findings and simulations using the FLUKA Monte Carlo code.

Summary: The FeCoW alloys exhibit unique properties and are suitable for various practical applications. The FeCoW NWs, electrodeposited in the AAO template, have a nanoscale porous structure. Increasing the W content significantly enhances the saturation magnetization of the NWs. The deposition potential also influences the composition, structure, and magnetic properties of the NWs.

Summary: Ag/Pd multilayers and AgPd alloyed ultrathin films were deposited on Corning glass by magnetron sputtering and formed self-assembled nanoparticles after annealing in air at 460 degrees C. Localized surface plasmon resonances were observed only for the Ag-rich samples, and the resonance position was found to depend on the initial film thickness. Theoretical calculations using the rigid coupled-wave analysis method were in suitable agreement with the experimental results.

Summary: This study engineered light-emitting composites by adding gold nanorods (AuNRs) suspension at various concentrations into the sol-gel process with europium-doped silica host matrices. The results showed that the addition of AuNRs suspension produced remarkable color changes in the luminescence of the samples towards the reddish-orange region, while the dissolution of AuNRs minimized the localized surface plasmon resonance effects on the luminescence. Therefore, the evaluation and selection of chemicals are critical factors for more efficient coupling between the localized surface plasmon resonance and the luminescence.

Summary: A surface lattice resonance (SLR) sensor based on crescent nanoarrays is proposed in this work, which can achieve a high figure of merit (FOM) by adjusting the structural parameters of the arrays. Experimental results show that the FOM can reach a level higher than 1000 RIU-1, and this sensor demonstrates great potential in trace substance detection.

Summary: The study investigates the optical properties of PVC/ZnO nanocomposite films. The results show that the optical properties of the films are dependent on the concentration of ZnO and the wavelength of light, and the optical parameters can be influenced by altering the concentration of non-annealed and annealed ZnO nanoparticles in the PVC matrix.

Summary: The UV-Vis optical behavior of nanocomposite films composed of PVP/PVA blend matrix and Al2O3 nanofiller was studied for potential optoelectronic device applications. The band gap values of the composites decreased nonlinearly with increasing Al2O3 content, while various optical parameters could be controlled by the filler concentration.
