The optical properties of nanostructures are rather important for designing plasmonic devices. In this work, the Ag-coated spherical dielectric nanoparticles (NPs), namely, Ag-SiO2-NPs, Ag-ZnO-NPs, and Ag-TiO2-NPs, were studied using a method finite-difference time-domain calculations. It was found that NPs start to exhibit unique different from Ag-NPs as thickness Ag shells is reduced be less ...

The application of Ag nanostructures to surface-enhanced Raman scattering (SERS) is hindered by their chemical instability. Fabrication of durable Ag-based SERS substrates is therefore of great significance in practical applications. In this work, ultrathin C-layer-encapsulated Ag nanoparticle arrays (UCL-Ag-NAs) are successfully fabricated on the surface of indium-tin-oxide (ITO) glass, using ...

Novel silver encapsulated nanocomposite zinc oxide/iron tetra-poly-vanadate (Ag-ZnO/Fe2V4O13) was synthesized with various wt% of (1.0–2.5 Ag) by cost-effective photo-deposition method under the irradiation ultraviolet-A (UV-A) light. The nanostructure Ag-ZnO/Fe2V4O13 explored characterization techniques. surface functionalities were confirmed Fourier transform infrared spectra and crystalline ...

Wastewaters of the textile industry, e.g., those generated in Gresik, Indonesia, are a possible threat to environment and should be treated before disposal. Photodegradation is more promising method overcome this problem than conventional methods such as biodegradation. ZnO widely used for photodegradation due its unique physical chemical properties stability. In study, Ag was loaded onto ZnO, ...

Self-Powered Photodetector A strategy to enhance the photothermal conversion of UV light by LSPR silver nanoparticles (Ag NPs) is proposed Jianping Meng, Zhou Li, and co-workers in article number 2200327. After decorating Ag NPs, photodetector based on Schottky junction ZnO nanowires (NWs) can detect with low power density. The enhanced performance attributed high-quality factor NPs wavelength ...

Given the increasing use of silver nanoparticles (Ag NP) by the food and food packaging industries, this study investigated potential consequences of Ag NP ingestion in intestinal epithelial C2BBe1 cells. Treatment of proliferating cells (<10,000 cells/cm(2)) with 0.25 μg/cm(2) (1.25 μg/mL) of 23 nm Ag NP for 24 h induced 15% necrotic cell death and an 80% reduction in metabolic activity and de...
