Summary: In this study, the progress of nanoengineering on noble metals and the extreme nonlinear optics within nanometric volumes are explored. Plasmonic nanostructures are found to offer a unique route for enhancing high-order harmonic generation and other nonlinear optical progress. The researchers demonstrated a strong third harmonic emission in zinc oxide microbelts through a strong localization of electromagnetic field caused by localized surface plasmon resonances. The intensity of third-harmonic generation was enhanced significantly in a composite of microbelts and Au nanoparticles, compared to the bare microbelts. Additionally, the polarization characteristics of the third-harmonic generation in the same system were improved significantly.

Summary: Organic thin film based excitonic nanostructures have shown great potential in resonant nanophotonics as an alternative to plasmonic systems. The concentration of excitonic molecules in the film plays a crucial role in realizing surface excitonic modes and optimizing their optical performance. Our study investigates the effect of molecular concentration on various surface excitonic modes and their performance in sensing and spectroscopy. The results show that the optical performance of excitonic systems can be tuned by adjusting the molecular concentration, unlike plasmonic systems. This research provides valuable information for the development of novel excitonic nanodevices in organic nanophotonics.

Summary: We report on the enhancement of reflection and diffraction induced by surface-plasmon-polariton (SPP) and strain-wave on an Au-covered segmented grating. The segmented grating has multiple SPP resonances at different optical wavelengths and the reflection changes from surface acoustic waves (SAWs) and longitudinal waves (LWs) are strongly enhanced near the SPP resonances. Furthermore, the diffraction changes induced by SAWs and LWs are larger compared to the reflection changes.

Summary: Various nanostructures capable of generating strong local electromagnetic fields have been extensively studied for plasmonic applications. In this research, pin-shaped gold nanodiscs were fabricated on silicon posts to decouple the optical near fields from the substrate. The optimal diameter of the silicon post was achieved through reactive-ion etching, resulting in a 3-fold increase in the electric field enhancement compared to similar structures on bulk silicon. The pin-shaped nanostructures showed a significant increase in the enhancement factor in SERS measurements. This work suggests a method of engineering 3D morphology to tune the substrate influence on plasmonic properties and develop efficient nanofabrication technologies.

Summary: This work demonstrates the enhancement in plasmonic sensing efficacy by spatially-localized functionalization on nanostructured surfaces, where probe molecules are concentrated in areas of high field concentration. SERS measurements on nanostructured surfaces with homogeneous and spatially-localized functionalization with thiophenol show that the Raman signal mainly originates from high field concentration areas. TERS measurements with 10 nm spatial resolution confirm the predicted field distribution profiles.

Summary: In this study, we for the first time observed and considered the plasmonic coupling between noble-metal and semiconductor nanostructures in metal/semiconductor heterostructures, using a W18O49/Ag heterostructure composed of Ag nanoparticles and W18O49 nanowires. The heterogeneous structure exhibited a broad and strong surface plasmon resonance (SPR) absorption in the visible wavelength range. Surface-enhanced Raman scattering (SERS) was used to investigate the interactions between metal SPR, semiconductor SPR, and the heterostructure's charge transfer process, revealing that the coupled SPR enhanced the heterostructure's internal charge transfer and SERS signals. A new coupled-plasmon-induced charge transfer mechanism was proposed to explain the improved charge transfer efficiency. This work provides insights for further studies on plasmonic effects and interfacial charge transfer in metal/semiconductor heterostructures.

Summary: We study the simultaneous narrowband and broadband light absorption enhancement of monolayer graphene on a metallic substrate with a periodic array of small holes. The absorption peaks of graphene are proven to stem from the hybrid modes of delocalized surface plasmon polaritons propagating on the substrate surface and localized magnetic plasmons confined within individual holes. The positions, maxima, and bandwidths of the absorption peaks can be tuned through changing the hole array period. The maximum absorption values at the narrowband and broadband peaks can reach up to 65% and 85%, respectively. The bandwidths of the absorption peaks can be conveniently adjusted, with the narrowband peak reduced to several nanometers and the broadband peak expanded to tens of nanometers.

Summary: Resonant optical nanomaterials, such as silicon, can manipulate highly confined guided waves in the form of surface plasmon polaritons (SPPs) on a subwavelength scale. It has been demonstrated that SPPs in ultrathin metal films can be efficiently launched due to the strong coupling between the Mie resonances of the nanoparticle and the SPP modes. By varying the particle size, the SPP excitation wavelength can be tuned across the entire near-infrared spectrum. Our results suggest that silicon nanoparticles may serve as scatterers of the SPPs supported by the film, paving the way for using high-refractive-index dielectric nanoantennas as compact elements for manipulating highly confined SPPs.

Summary: High-quality hexagonal NaYF4:Er/Yb particles and monodisperse copper(I) sulfide nanoparticles were synthesized using solvothermal and hot-injection methods, respectively. A semiconductor-insulator-semiconductor (SIS) hybrid structure was constructed for upconversion luminescence (UCL). The UCL of SIS was significantly enhanced due to the amplified optical field caused by the localized surface plasmon resonance (LSPR) effect of copper(I) sulfide nanoparticles and the local effect of the copper(I) sulfide film on the excited light.

Summary: In this study, a novel core-shell hybrid structure of (mCu2-xS, NaYF4:Er/Yb)@ porous silica composites was constructed for upconversion luminescence (UCL). The amplified internal optical field of the composites, induced by the localized surface plasmon resonance (LSPR) coupling between Cu2-xS nanoparticles, allowed more photons to participate in the upconversion process. The UCL intensity of the composites in the emission band of green was 45 times higher than that of NaYF4:Er/Yb@SiO2, and the quantum yield of the composites was 1.32%. The UCL enhancement mechanism of the composites was also investigated.
