“…Cronin's group has attributed photocatalytic enhancement to this plasmonic local electric field enhancement 44, 61, 66. Several other groups have also adopted the local electric field enhancement mechanism 45, 49, 60, 64, 98–100. Lu et al ascribed a 2.3‐fold increase in 2,4‐dichlorophenol degradation catalyzed by Au nanoparticle/TiO 2 to the enhanced light harvesting caused by the surface plasmon resonance 49.…”

“…Liu et al observed enhanced photocurrents in the water splitting reaction under visible illumination by depositing Au nanoparticles on top of anodic TiO 2, with enhancement factors of 5 and 66 at 532 nm and 633 nm, respectively 61. Duan et al also reported similar enhancement for Ag nanoparticles on CdS with a particular emphasis on the SiO 2 intermediate layer between CdS and Ag, which plays an important role in tuning the plasmon resonance peak 60. Torimoto et al also demonstrated enhanced photocatalytic activity for photocatalytic water splitting by deposition of CdS on Au@SiO 2 particles 64.…”

In the past decade, the surface plasmon resonance of Ag and Au nanoparticles has been investigated to improve the efficiency of photocatalytic processes. The photocatalytic production of fuels is particularly interesting for its ability to store the sun's energy in chemical bonds that can be released later without producing harmful byproducts. This Feature Article reviews recent work demonstrating plasmon‐enhanced photocatalytic water splitting, reduction of CO2 with H2O to form hydrocarbon fuels, and degradation of organic molecules. Focus is placed on several possible mechanisms that have been previously discussed in the literature. A particular emphasis is given to several aspects of these mechanisms that are not fully understood and will require further investigation.

of surface plasmons with an incoherent light source and the detection with a portable spectrometer; however, the sensitivity of these devices is an order of magnitude lower than conventional SPR sensors. [7] Here, we report a new nanoplasmonic resonance sensor design that shows a unique interactive plasmonic-photonic resonance effect: only resonance peak intensity variation, not a plasmon resonance wavelength shift, is observed in the far field as a function of the optical refractive index (RI) on the superstrate when a periodic plasmonic nanostructure and a multilayer nanocavity are combined. Multilayer plasmonic structures have been investigated for on-chip photonic devices, such as multilayered plasmonic waveguides. [8] Metal-insulator-metal (MIM) surface plasmon waveguides have been studied for refractometric detection. [9] In addition, the localized surface plasmon resonance (LSPR) effect has been used with multilayered geometries to increase light-induced catalytic activity of materials such as palladium. [10] The study of dielectric films and MIM structures combined with an EOT substrate has been reported previously. [11] However, these prior works focused on surface enhanced Raman spectroscopy applications or on the plasmon resonance peak shift of nanohole arrays and the sensitivity of these structures to superstrate RI changes was lower than conventional EOT devices.The new hybrid nanoplasmonic-nanocavity sensor that we utilize here is based on a 3D plasmonic nanocup resonator structure, which consists of a nanostructured polymer substrate with a deposited gold (Au) layer. [12] To form a nanocavity A sensor design and sensing method based on plasmonic-photonic interactions that occur when a nanocavity array is embedded in a 3D tapered nanocup plasmonic substrate are reported. This device enables highly sensitive detection of refractive index changes based on changes to the transmission peak intensity without shift in the resonance wavelength. Unlike conventional plasmonic sensors, there is a consistent and selective change in the transmission intensity at the resonance peak wavelength with no spectral shift. In addition, there are wavelength ranges that show no intensity change, which can be used as reference regions. The fabrication and characterization of the plasmonic nanocavity sensor are described and also advanced biosensing is demonstrated. Simulations are carried out to better understand the plasmon-photonic coupling mechanism. This nanocavity plasmonic sensor design has a limit of detection of 1 ng mL −1 (5 × 10 −12 m) for the cancer biomarker carcinoembryonic antigen (CEA), which is a significant improvement over current surface plasmon resonance systems, and a dynamic range that is clinically relevant for human CEA levels.

“…[1][2][3] Surface plasmons are collective excitations of the electrons at the interface between a conductor and an insulator and are described by evanescent electromagnetic waves that are not necessarily located at the interface. [4][5][6] The properties of LSPR depend largely on the shape and size of the nanoparticles as well as the refractive index of the surrounding medium. 7,8 The optical responses associated with LSPR in metallic nanoparticles with di®erent structures have been investigated 9 and it is known that only one plasmonic resonance peak is generated from spherical nanoparticles, while two or more plasmonic resonance peaks can occur in other kinds of nanostructures such as nanodimers, nanorods and core/shell structures.…”

Multilayered nanoshells have attracted much attention due to their unique optical, electronic and magnetic properties. In this work, numerical calculation using discrete dipole approximation (DDA) is conducted to investigate the quad-layered metal nanoshell consisting of a particle with a dielectric silica (SiO 2 ) core, inner cadium sul¯de (CdS) shell, middle indium tin oxide (ITO) shell and outer metal silver (Ag) shell. The phenomenon is interpreted by plasmon hybridization theory and the Ag-ITO-CdS-SiO 2 multilayered nanoshells are studied by extinction spectra of localized surface plasmon resonance. The variation in the spectrum peak with nanoparticle thickness and refractive index of the surrounding medium is derived. The electric¯eld enhancement contour around the nanoparticles under illumination is analyzed at the plasmon resonance wavelength. The j!
