“…Recently, aluminum nanoparticles were investigated in typical plasmonic applications, i.e. efficiency enhancement in solar cells or photodetectors [15][16][17], fluorescence enhancement [18,19] or surface-enhanced Raman spectroscopy [20]. Aluminum was also shown to be a promising candidate for a pixelized color representation, which could find its way into display applications by exploiting the fact that aluminum plasmon resonances can cover the entire visible spectrum.…”

Abstract:As a key feature among metals showing good plasmonic behavior, aluminum extends the spectrum of achievable plasmon resonances of optical antennas into the deep ultraviolet. Due to degradation, a native oxide layer gives rise to a metal-core/oxide-shell nanoparticle and influences the spectral resonance peak position. In this work, we examine the role of the underlying processes by applying numerical nanoantenna models that are experimentally not feasible. Finite-difference time-domain simulations are carried out for a large variety of elongated single-arm and two-arm gap nanoantennas. In a detailed analysis, which takes into account the varying surface-to-volume ratio, we show that the overall spectral shift toward longer wavelengths is mainly driven by the higher index surrounding material rather than by the decrease of the initial aluminum volume. In addition, we demonstrate experimentally that this shifting can be minimized by an all-inert fabrication and subsequent proof-of-concept encapsulation.

“…The generated photocurrent density (J sc ) increases with the introduction of Ag NPs, which is found to be 44 and 19 % higher than the reference device (device 1) for one and two SILAR cycles, respectively, as shown in Table 1; thus, showing the electron transport efficiency in the TiO 2 /dye/electrolyte interface is improved. With the increase in the amount of incorporated Ag NPs, increase in the recombination probability arises and leads to the decline of photocurrent density [20] and, as a result, reduces the PCE of the DSSCs when the SILAR cycles increased from one to two. Considering the size and aggregation state of Ag NPs as observed in Fig.…”

“…Also, the recombination reaction creates an internal short-circuit throughout the bulk of the photoanode layer [32]; as a result, the device shows a lower PCE with two SILAR cycles. Also, the scattering effect may contribute to the decline, but the plasmonic effect still dominates because of the relatively small size of the nanoparticles [20].…”

“…Noble plasmonic metal nanostructures, such as gold (Au), silver (Ag) [18,19], aluminum (Al) [20], their alloys [16], and their core-shell formation [21][22][23][24][25], have been incorporated into DSSCs to effectively utilize the incident photon and improve cell performance. Many methods, both chemical and physical categories, including, wet chemical [26], polyol process [27], seed-mediated growth [28], photochemical [29], sonochemical [30], electrochemical [31], bioinspired [32], sputtering [33], and laser ablation [34], which have been, hitherto, reportedly employed to synthesize various plasmonic Ag nanostructures, possess one disadvantage or the other, such as toxic reducing agents, impurities, organic solvents, or may require special condition like high-temperature or low-pressure environment, and sometimes expensive and time-consuming procedures may be involved [35].…”

Dye-sensitized solar cells (DSSCs) comprising mesoporous TiO 2 films and betalain pigments extracted from red Bougainvillea glabra flower as natural dye sensitizers were fabricated and enhanced by the intercalation of the plasmonic silver nanoparticles (Ag NPs) into the pores of mesoporous TiO 2 electrodes by successive ionic layer adsorption and reaction (SILAR) method. The TiO 2 / Ag NPs composite films were characterized by SEM and UV-Vis spectroscopy. I-V characteristics of the devices were measured by solar simulator (AM1.5 at 100 mW/ cm 2 ). The incorporation of the Ag nanoparticles into the pores of mesoporous TiO 2 electrodes with one SILAR deposition cycle of the Ag NPs produced the best plasmonic enhanced-DSSC giving a short-circuit current density (J sc ), fill factor (FF), and power conversion efficiency (PCE) of 1.01 mA cm -2 , 0.77, and 0.27 %, respectively. This development amounts to 50 % efficiency enhancement over the reference DSSC that had a short-circuit current density (J sc ), fill factor (FF), and power conversion efficiency (PCE) of 0.7 mA cm -2 , 0.57, and 0.18 %, respectively.

Recent advances in deep-ultraviolet (DUV) spectroscopy and related technologies have targeted the observation of photon-electron coupling in widebandgap materials. The energy of a single photon of DUV light is high enough to excite an electron to the first or higher electronic levels of a material. This is the main drawback of DUV spectroscopy for soft materials since higher-order excitations are often followed by photodamage. At the same time, high photon energy can be an advantage from the viewpoint of energy conversion between photons and electrons in a wide-bandgap material. DUV spans a marginal range of wavelengths that can occur under atmospheric pressure in sunlight on Earth. Its high photon energy and availability are expected to lead to great applications in DUV photonics. As mentioned in the previous chapter, photons couple with free electrons in metals at the nanometer scale, exhibiting a localization and enhancement effect known as localized surface plasmon resonance (LSPR). LSPR has been exploited in many scientific and industrial fields, such as sensors, optical waveguides, high-sensitivity optical detection, and high-resolution microscopy (Willets and Van Duyne, Rev Phys Chem 58:267-97, 2007). In this chapter, I review some important aspects of DUV photons, mainly focusing on DUV-LSPR applications in, for example, photocatalysis, photovoltaic devices, and light-emitting diodes (LEDs), including enhancement mechanisms such as carrier generation, photoexcited lifetime modifications, emission pattern controls, and coulombic forces.Keywords Localized surface plasmon resonance • Plasmonic nanostructure • Photocatalysis • DUV-LED DUV Plasmonic NanostructuresFor efficient coupling between a photon wave vector and free electrons in a material, the specific shape and size of nanostructures, the so-called plasmonic nanostructures, should be prepared to host LSPR. In order to achieve LSPR in Y. Saito ( )
