“…On the other hand, the disk, rod and toroidal shapes show a superior thermal response in all aspects (magnitude, spectral tunability and response time). The disk shows a better performance in terms of heating however the optimal geometry requires an especially thin height of 10 nm with a radius of 50 nm to achieve the maximum temperature, resulting in a challenging fabrication process [45]. In the case of the nanorod, its thermal response displays a redshift with respect to the disk.…”

Photoinduced hyperthermia is a cancer therapy technique that induces death to cancerous cells via heat generated by plasmonic nanoparticles. While previous studies have shown that some nanoparticles can be effective at killing cancer cells under certain conditions, there is still a necessity (or the need) to improve its heating efficiency. In this work, we perform a detailed thermoplasmonic study comparing the most effective nanoparticle geometries up to now with a dougnhut-shaped nanoparticle, demonstrating that the latter exhibits an outstanding tuneable photothermal response in realistic illumination conditions, i.e., partially polarized light. Furthermore, we show that nanoparticle heating in microfluidic environments, i.e. nanoparticles suffering arbitrary rotations, strongly depends on the particle orientation with respect to the illumination source, a circumstance often neglected in photothermal applications. We conclude that heating of nanodoughnuts depends weakly on orientation and light depolarization, being therefore ideal candidates for photothermal therapy applications. Finally, we present a nanodoughnut designing guide, covering a wide range of toroid designs, which can help on its experimental implementation.

“…Both the current density and the incident photon-to-electron conversion efficiency increased drastically for those samples with Al NPs due to the contribution of the enhanced local field from the LSPR mode of Al. Recently, Liang et al also utilized aluminum nanohole arrays in organic photovoltaics [40]. A self-assembled nanoparticle template was used to fabricate the size-tunable Al nanodisk array on the top of a TiO 2 film.…”

Solar water splitting by semiconductor based photoanodes and photocathodes is one of the most promising strategies to convert solar energy to chemical energy to meet the high demand for energy consumption in modern society. However, the state-of-the-art efficiency is too low to fulfill the demand. To overcome this challenge and thus enable the industrial realization of a solar water splitting device, different approaches have been taken to enhance the overall device efficiency, one of which is the incorporation of plasmonic nanostructures. Photoanodes and photocathodes coupled to the optimized plasmonic nanostructures, matching the absorption wavelength of the semiconductors, can exhibit a significantly increased efficiency. So far, gold and silver have been extensively explored to plasmonically enhance water splitting efficiency, with disadvantages of high cost and low enhancement. Instead, non-noble plasmonic metals such as aluminum and copper, are earth-abundant and low cost. In this article, we review their potentials in photoelectrolysis, towards scalable applications.

Plasmonic metal nanostructures, possessing unique surface plasmon resonance properties, show excellent capabilities for light trapping and coupling. On this basis, various plasmonic metal nanostructures offer extraordinary opportunities to promote the conversion efficiency of solar energy to electric energy, hydrogen energy or thermal energy, etc. In this review article, we highlight a number of recent research achievements on the rational design of plasmonic metal nanostructures so as to maximize the utilization of the entire solar spectrum. Compared with single metal nanoparticle, multiplex (such as multi-compositions, sizes, or shapes) nanoparticle structures emphasize advantages in broadening absorption range and improving light-utilization efficiency. This review is ended up with discussions about the challenges in this research field and proposals of some prospects for future directions.
