Summary: This paper investigates the dynamics of hybridized states from 2D Ruddlesden-Popper perovskites coupled to plasmonic nanoparticle lattices. The coupling strength can be modulated by varying the perovskite film thickness or the superstrate refractive index. The study shows that both upper and lower polaritons have shorter lifetimes than excitons and polaritons exhibit faster excited-state dynamics when they have access to additional energy transfer channels.

Summary: This study demonstrates the photoelectrocatalytic activity for hydrogen evolution reactions using strongly coupled bimetallic core-shell nanoparticle arrays. Fabricating large-area Cu-Pt nanoparticle lattices, the coupled lattices were shown to support two different types of plasmon modes, leading to increased catalytic activity under white-light illumination. Comparing the two plasmon modes at different wavelength ranges, surface lattice resonances (SLRs) exhibited two-fold activity enhancement over localized surface plasmons.

Summary: This study compares the luminescence decay dynamics of single CdSe nanoplatelets, clusters of a few platelets, and self-assembled chains. The luminescence decay becomes faster as the number of stacked platelets increases, indicating the FRET-mediated effect of quenchers. Additionally, a slow decay component is observed for both single platelets and platelet chains, suggesting trapping-detrapping mechanisms in nearby trap states. Toy models are developed to analyze the effects of FRET-mediated quenching and trapping on decay curves.

Summary: This review discusses the integration of plasmonic and dielectric metasurfaces with emissive or stimuli-responsive materials, enabling control of light-matter interactions at the nanoscale. Metasurfaces offer the ability to manipulate electromagnetic waves at the subwavelength level, while the combination with nanoscale emitters allows for enhanced photoluminescence, nanoscale lasing, controlled quantum emission, and formation of exciton-polaritons. Additionally, the use of functional materials that respond to external stimuli enables the engineering of tunable nanophotonic devices. Emerging metasurface designs, such as surface-functionalized, chemically tunable, and multilayer hybrid metasurfaces, hold promise for various applications including photocatalysis, sensing, displays, and quantum information.

Summary: This research describes the strong coupling between a plasmonic nanoparticle lattice cavity and Soret excitons in a metal-organic framework film. By infiltrating MOF pores with solvents of different refractive index, the lower polariton mode can be spectroscopically tuned. Transient absorption spectroscopy can resolve both the lower and upper polariton modes, with an estimated Rabi splitting of about 300 meV, which is nearly twice the splitting of other plasmonic cavity-organic emitter systems. The polariton modes decay faster than the uncoupled exciton. This hybrid system highlights the advantages of open plasmonic cavities for tunable coupling, as well as the usefulness of transient absorption spectroscopy in identifying polariton modes.

Summary: This paper presents a method to generate hierarchical wrinkles in two-dimensional electronic materials, allowing for spatial control over adjacent wavelengths. A rigid fluoropolymer mold was used to pattern sacrificial polymer skin layers on various 2D materials, resulting in 2D material wrinkles with wavelengths proportional to the local skin thickness. The generation of second-generation wrinkles was also demonstrated by applying subsequent cycles of polymer skin coating, strain relief, and removal. This area-specific hierarchical wrinkling enables engineering of the local properties of 2D materials and their heterostructures.

Summary: An ultralong-range coupling was demonstrated between photonic lattices in bilayer and multilayer moire architectures, which is mediated by dark surface lattice resonances in the vertical direction. Two-dimensional plasmonic nanoparticle lattices enable twist-angle-controlled directional lasing emission, even when the lattices are spatially separated by distances exceeding three orders of magnitude of lattice periodicity. The discovery of far-field interlattice coupling opens the possibility of using the out-of-plane dimension for optical manipulation on the nanoscale and microscale.

Summary: By integrating two-dimensional lead halide perovskites with plasmonic nanoparticle arrays, we have established an open and versatile exciton-polariton platform, where excitons hybridize with surface lattice resonances in the strong coupling regime. We directly observed enhanced exciton transport and demonstrated an improvement of exciton migration by more than one order of magnitude. We proposed a polariton-mediated exciton transport model and obtained an average polariton velocity of approximately 1 x 10^6 m/s for states with a photonic fraction of about 40%.

Summary: This paper presents a nanofabrication procedure that can generate multiscale substrates with quasi-random microregions of nanoparticle arrays having different periodicities and metals. The approach combines large-area nanoparticle array fabrication with solvent-assisted wrinkle lithography to control the fill factors of the arrays. It has been demonstrated that multimetallic nanoparticle arrays can function as nanoscale cavities for lasing action at low fill factors, and can exhibit lasing responses over visible and near-infrared wavelengths when multiple arrays with different periodicities are combined.
