Local Growth Mediated by Plasmonic Hot Carriers: Chirality from Achiral Nanocrystals Using Circularly Polarized Light

Lucas Besteiro et al.

Summary: This study explores the possibility of growing chiral plasmonic nanocrystals from nonchiral seeds using circularly polarized light, and introduces a novel theoretical methodology to simulate realistic photogrowth processes. The results demonstrate strongly anisotropic and chiral growth of nanocrystals, even for those with subwavelength sizes.

Sequential Symmetry-Breaking Events as a Synthetic Pathway for Chiral Gold Nanostructures with Spiral Geometries

Spencer D. Golze et al.

Summary: The study introduces a light-driven solution-based synthesis approach to produce helical gold spirals from substrate-bound seeds. This growth mode relies on three separate symmetry-breaking events: seeds with planar defects, a capping agent that impedes early growth, and Coulombic repulsion when charged growth fronts collide.

Bottom-Up Synthesis of Helical Plasmonic Nanorods and Their Application in Generating Circularly Polarized Luminescence

Jiaqi Chen et al.

Summary: This study introduces a chemical strategy for synthesizing intrinsically helical plasmonic nanorods with strong and tailorable plasmonic circular dichroism responses, analyzing the influence of structural parameters on the responses. The depth of the pitch was found to have the greatest impact on the response, and these nanorods were found to induce circularly polarized luminescence of achiral luminophores. The chiral plasmonic nanostructure produced in this study has potential applications in chiral sensors, catalysis, and displays.

Symmetry in Seeded Metal Nanocrystal Growth

Sara E. Skrabalak

Summary: Symmetry plays a crucial role in nanomaterials, with seeded methods enabling the synthesis of complex multimetallic crystals for applications in plasmonics and catalysis. The underlying symmetry of seeds can be predictably transferred to final crystals during overgrowth, but can also be reduced in a controlled manner.Some key factors affecting symmetry preservation or reduction during seeded crystal growth include the concentrations of metal precursors and capping agents.
