Surface-enhanced Raman spectroscopy (SERS) is an ultrasensitive surface analysis technique that widely used in chemical sensing, bioanalysis, and environmental monitoring. The design of the SERS substrates crucial for obtaining high-quality signals. Recently, 2D transition metal dichalcogenides (2D TMDs) have emerged as high-performance due to their superior stability, ease fabrication, biocompatibility, controllable doping, tunable bandgaps excitons. In this review, a systematic overview...
Abstract Plasmonic materials can generate strong electromagnetic fields to boost the Raman scattering of surrounding molecules, known as surface-enhanced scattering. However, these are heterogeneous, with only molecules located at ‘hotspots’, which account for ≈ 1% surface area, experiencing efficient enhancement. Herein, we propose patterned plasmonic trimers, consisting a pair dimers bilateral sides and trap particle positioned in between, address this challenge. The trimer configuration...
Plasmon-induced oxidation has conventionally been attributed to the transfer of plasmonic hot holes.

Surface-enhanced Raman scattering (SERS) is renowned for amplifying signals, with electromagnetic mechanism (EM) enhancement arising from localized surface plasmon resonances and chemical (CM) as a result of charge transfer interactions. Despite the conventional emphasis on EM plasmonic effects, recent findings highlight significance CM when noble metals appear smaller entities. However, threshold size metal clusters/particles corresponding to switch in SERS mechanisms not clear at present....
Abstract Plasmonic catalysis employs nanomaterials to mediate the conversion of photon energy into localized electromagnetic fields, hot carriers, and thermal energy, facilitating molecular transformations under mild conditions. Understanding mechanisms governing plasmonic effects is crucial for optimizing yield selectivity in catalysis. However, challenges persist elucidating role field due complex interactions among various contributing mechanisms. This study introduces Au@Al 2 O 3...

The plasmonic metal/semiconductor heterojunction provides a unique paradigm for manipulating light to improve the efficiency of materials. Previous studies suggest that improvement originates from enhanced carrier exchanges between component and molecules. This viewpoint, known as chemical mechanism, is reasonable but insufficient, because construction will lead charge redistribution in cause changes its physical characteristics. Herein, we try clarify these are decisive factors specific...
