Plasmonic nanocrystals with complex shapes for photocatalysis and growth: Contrasting anisotropic hot-electron generation with the photothermal effect

Autor: Artur Movsesyan, Eva Yazmin Santiago, Sven Burger, Miguel A. Correa‐Duarte, Lucas V. Besteiro, Zhiming Wang, Alexander O. Govorov

In plasmonics, and particularly in plasmonic photochemistry, the effect of hot-electron generation is an exciting phenomenon driving new fundamental and applied research. However, obtaining a microscopic description of the hot-electron states represe

Efficiency of Hot-Electron Generation in Plasmonic Nanocrystals with Complex Shapes: Surface-Induced Scattering, Hot Spots, and Interband Transitions

Autor: Xiang-Tian Kong, Lucas V. Besteiro, Miguel A. Correa-Duarte, Alexander O. Govorov, Zhiming Wang, Eva Yazmin Santiago

Publikováno v: ACS Photonics. 7:2807-2824

The generation of hot electrons is an intrinsic property of all plasmonic nanocrystals under illumination. However, the number of such excited electrons will strongly depend on the shape, material,...

Colloidal titanium nitride nanobars for broadband inexpensive plasmonics and photochemistry from visible to mid-IR wavelengths

Autor: Sourav Rej, Eva Yazmin Santiago, Olga Baturina, Yu Zhang, Sven Burger, Stěpán Kment, Alexander O. Govorov, Alberto Naldoni

Publikováno v: Nano Energy. 104:107989

Developing colloidal plasmonic nanomaterials with high carrier density that show optical resonances and photochemical activity extending from the visible to the mid-infrared (MIR) ranges remains a challenging pursuit. Here, we report the fabrication

Electronic Structure of the Plasmons in Metal Nanocrystals: Fundamental Limitations for the Energy Efficiency of Hot Electron Generation

Autor: Jiachen Sun, Alexander O. Govorov, Zhiming Wang, Lucas V. Besteiro, Le Chang, Eva Yazmin Santiago, Stephen Gray

Publikováno v: ACS Energy Letters. 4:2552-2568

This Review discusses the electronic structure of plasmonic resonances in metal nanostructures, clarifying existing misconceptions on the topic. Here we underscore the key property of the plasmonic response in metal nanocrystals: the plasmon and its

Dispersive Properties of Mesoporous Gold: van der Waals and Near-Field Radiative Heat Interactions

Autor: J. E. Pérez-Rodríguez, Eva Yazmin Santiago, Raul Esquivel-Sirvent

Publikováno v: The Journal of Physical Chemistry C. 121:12392-12397

We present a theoretical calculation of the dispersive interaction of mesoporous Au sponges. The ability to manipulate the dielectric function of the sponge by varying its porosity is applied to the calculation of the Hamaker constant using Lifshitz
