Plasmonic nanostructures show great promise for sensing because their nanoscale confined light fields are sensitive to the change in the surroundings. Conventional plasmonic sensors based on surface plasmon polaritons (SPPs) and localized surface plasmon resonances (LSPRs) have inspired considerable progress in sensing but still suffer from an oblique incidence or moderate sensitivity. This review focuses on how the rational design of novel plasmonic nanostructures can enable high‐performance sensing. Patterned nanostructures such as nanoparticle (NP) lattices to support surface lattice resonances (SLRs) and plasmonic nanogaps with nanogap modes are emerging to overcome the sensing limitations of SPP and LSPR. Moreover, hybrid nanostructures of plasmonic components with functional materials, such as metal‐organic frameworks, 2D materials, oxides, and polymers, show opportunities to further improve sensitivity and selectivity. In addition, plasmonic nanolasing and resonance modes from new materials exhibit appealing features for sensing. It is expected that further studies on plasmonic nanostructures with low‐loss materials, chirality characteristics, novel devices, and advanced fabrications will provide outlooks for high‐performance sensing.

“…This has provided a rich library for the design of various antenna/semiconductor heterointerfaces, which imparts an additional degree of freedom for the regulation of the dynamic process of photocarriers that is critical to hot carrier extraction. Thus far, a number of competitive non-noble plasmonic competitors have emerged including Al, [84] Cu, [85] Si, [86] Ge, [87] TiN, [88] Cu x S, [89] Cu 2-x Se, [90] MoO 3-x , [91] WO 3-x , [92] MXene, [93] and so on.…”

The distinctive layered crystal structures and diverse properties of 2D layered materials (2DLMs) have established them as prospective building blocks for implementing next‐generation optoelectronics. One critical predicament in terms of light sensing is the weak absorption caused by the atomic‐scale thickness, as well as the limited effective wavelength range/low spectral selectivity constrained by the intrinsic band structures. Despite the fact that numerous noble metal antennas are harnessed for enhancing the light–matter coupling, they suffer from exorbitant cost and narrow resonant optical windows. To this end, a number of non‐noble plasmonic optical antennas have been developed to improve the light‐sensing properties of 2DLM photodetectors, and tremendous advances have been accomplished. Herein, a comprehensive overview of this subject is provided based on four aspects; namely, non‐noble metal antenna promoted 2DLM photodetectors, heteroatom doped semiconductor antenna promoted 2DLM photodetectors, non‐stoichiometric semiconductor antenna promoted 2DLM photodetectors, and MXene antenna promoted 2DLM photodetectors. The focus is on the device structures, preparation, and underlying mechanisms. In the end, the challenges are highlighted, and potential strategies addressing them are proposed, which aim to navigate the upcoming exploration in the related domains and fully exert the pivotal role of non‐noble plasmonic optical antennas toward advancing 2DLM photodetectors.

“…Plasmonic nanostructures belong to an emerging class of materials whose optical properties take advantage of localized and delocalized surface plasmon (SP) resonance, which gives rise to large enhancement of the electromagnetic field, subwavelength confinement, and thermal effects. − They have numerous applications, such as in optical sensors, nonlinear optical devices, biosensors, and bactericidal materials. − SPs were previously considered to arise from metallic structures and to be controlled by the shapes, sizes, and dielectric environments of such materials. Ongoing research has demonstrated that SPs in highly doped semiconductors, perovskites, transparent metal oxides, and metal nitrides/dichlorchalcogenides are of the same status as those seen with metallic structures. − …”

Metal silicides are suitable for semiconductor applications ranging from contact junctions to gate materials due to their inherent compatibility with silicon technology. It was deemed that they are not suitable for surface plasmon (SP) applications because they exhibit larger optical losses than other plasmonic materials. Here, metal silicide nanostructures were exploited for light heating to utilize their SP-enhanced absorption loss. The particles, mainly in the crystalline CoSi phase, were prepared by laser ablation in liquid for the first time despite the challenges arising from complex phase behavior and multiple stoichiometries of the metal silicide. The CoSi particles showed excellent photothermal conversion efficiency (30.5% in the infrared range) as plasmonic absorbers, which makes metal silicides promising in versatile applications such as plasmon-enhanced catalysis, heat assisted magnetic recording, and thermophotovoltaics.
