Summary: In this study, the linear and nonlinear optical behavior of cobalt phthalocyanine (CoPc) in the combined local fields of plasmonic and photonic cavity modes were investigated. A planar microcavity was created using polymeric layers and embedded with CoPc/Au nanocomposites. The strong field strengths caused by the cavity photon-plasmon coupling significantly enhanced the nonlinear optical absorption of CoPc. The proposed system can act as an angle-tunable nonlinear optical switch with potential applications in photonics.

Summary: In this work, a method for fabricating large-area gold nanoparticle superlattices with subnanometer interparticle gaps is demonstrated. The electrical transport measurements reveal significant variations in the nanogap conductance, while in situ optical reflectance measurements show enhanced plasmonic capacitive coupling with decreasing interparticle gap distance. The resulting superlattices also exhibit tunable effective refractive index and extreme field confinement in the high-density subnanometer plasmonic gaps.

Summary: We demonstrate that a weak nonlinear response of a probe beam can be modulated and controlled by a pump beam in plasmonic nanosuspensions, resulting in the generation of ring-shaped patterns. Gold nanosuspensions with strong nonlinear response is used as the medium for beam manipulation. The dynamics of hollow beam generation are examined in different nanosuspensions. This study enhances the understanding of nonlinear light-matter interactions and has potential applications in light control and optical limiting.

Summary: This study introduces a chemical strategy for synthesizing intrinsically helical plasmonic nanorods with strong and tailorable plasmonic circular dichroism responses, analyzing the influence of structural parameters on the responses. The depth of the pitch was found to have the greatest impact on the response, and these nanorods were found to induce circularly polarized luminescence of achiral luminophores. The chiral plasmonic nanostructure produced in this study has potential applications in chiral sensors, catalysis, and displays.

Summary: This work presents the use of a water-soluble conjugated polymer as a surface ligand for gold nanoparticles to achieve plasmonic catalysis under visible light. The metal-polymer heterojunction, rich in sulfonate functional groups, contributes to the interaction between electron-donor molecules and the plasmonic photocatalyst. The tight binding of the polymer to the gold surface eliminates the need for conventional transition-metal surface cocatalysts and enhances the reactivity.

Summary: This study demonstrates a plasmonic catalyst of nitrogen-doped carbon-encapsulated metallic Co nanoparticles with excellent catalytic activity for selective oxidation of alcohols under mild conditions. The plasmonic Co@NC catalyst achieves a 7.8-fold improvement compared to thermocatalysis, operating effectively with light as the only energy input. Detailed characterization reveals that the absorbed light energy excites the d states of metallic Co, generating energetic electrons and activating molecular oxygen and alcohol molecules adsorbed on its surface. The formation of multi-type radical species facilitates the direct and efficient production of esters.

Summary: Electron paramagnetic resonance (EPR) coupled with the spin trapping technique is commonly used to identify radicals and investigate reaction mechanisms in advanced oxidation processes (AOPs). However, unexpected spin trapping artifacts in highly oxidizing environments can lead to misinterpretation of AOPs mechanisms. This study reveals previously unrevealed reactions between perox-ydisulfate (PDS) and 5,5-dimethyl-1-pyrroline N-oxide (DMPO) or N-tert-butyl-alpha-phenylnitrone (PBN), and proposes the formation routes of the detectable adducts. The findings emphasize the importance of selecting appropriate spin traps and conducting control tests when studying catalytic oxidation mechanisms under highly oxidizing conditions.
