Summary: In this work, composite thin films consisting of titanium dioxide and noble metal nanoparticles (silver, gold, and bimetallic silver/gold alloys) were synthesized using RF magnetron sputtering. The resulting thin films were characterized using various techniques, including TEM, SEM, XRD analysis, and Raman spectroscopy. The study showed that annealing in an argon atmosphere induced crystallization in the initially amorphous TiO2 matrix. The composite films exhibited two light absorption regions, one associated with localized surface plasmon resonance (LSPR) phenomena and the other due to the energy band gap. The composition of the metal nanoparticles could be adjusted to tune these parameters in the composite films.

Summary: In this paper, the enhanced performance of organic solar cells (OSCs) with low band gap photoactive layers and 2D arrays of plasmonic nanostructures embedded at the back of the OSCs is demonstrated. The performance of the OSCs containing different plasmonic nanostructures is compared through finite-difference time-domain (FDTD) simulations. The results show that OSCs with 2D arrays of Ag nano-parabola at the back of the solar cell exhibit significantly improved short circuit current density and power conversion efficiency compared to planar OSCs, due to enhanced light scattering near the localized plasmon resonance of the metallic nanostructures.

Summary: The multishell-structured NaYF4:Yb,Tm,Nd@NaYF4:Yb,Nd@SiO2/Ag@TiO2 (UC@SiO2/Ag@TiO2) nano-spheres were prepared for the first time, showing enhanced NIR-triggered photocatalytic activity under the synergistic effect of upconversion and plasmons. The incorporation of Yb/Nd shell significantly improved the upconversion luminescence (UCL) efficiency of NaYF4:Yb,Tm,Nd@NaYF4:Yb,Nd upconversion nanophosphors (Yb/Tm/Nd@Yb/Nd UCNPs), and the addition of Ag nanoparticles further enhanced the UCL intensity due to the plasmon resonance effect. The final UC@SiO2/Ag@TiO2 exhibited higher photocatalytic activity and antibacterial activity compared to UC@SiO2@TiO2.

Summary: In this study, the effects of dielectric coated plasmonic metal nanoparticles on solar absorption enhancement in perovskite thin films were numerically investigated. Surprisingly, a further absorption enhancement can be achieved when using thin dielectric coating of high refractive index, while an absorption reduction may occur when using thick dielectric shells of low refractive index. These anomalous effects provide new insights into the design of plasmonic solar cells.

Summary: Ag nanoparticles significantly enhance the photocatalytic activity of self-organized TiO2 nanotube structures. In this study, novel Ag/TiO2 tube-in-tube fibers were prepared using a simple electrospinning technology and calcination process. As a photocatalyst, the composite efficiently catalyzes the photodegradation of the model organic pollutant, rhodamine B, under visible light irradiation, showing superior photocatalytic activity compared to undoped TiO2 tube-in-tube fibers. This enhancement is attributed to the plasmonic characteristics of Ag nanoparticles, which promote light absorption and charge transfer feasibility. The simple, low-cost, and green fabrication route of the composite provides a novel means for preparing similar materials, holding great promise for wider application in the future.

Summary: Several hybrid composite photoanodes consisting of easily synthesizable and cost-effective La0.6Sr0.4CoO3 nanoparticles combined with TiO2 nanoparticles were investigated for their light-harvesting properties in dye-sensitized solar cells. By adding pure inorganic perovskite La0.6Sr0.4CoO3 and plasmonic silver nanoparticles decorated La0.6Sr0.4CoO3 into the TiO2 photoanodes, the efficiency of the DSSCs was significantly increased.
