Title: Phonon-induced plasmon-exciton coupling changes probed via oscillation-associated spectra

Abstract

Coherent vibrations detected in optical experiments can offer insights into material properties and electronic interactions, but also yield complex time-dependent optical signatures, especially in hybridized systems. In this work, we conform to techniques from studies on vibrational wave packets in molecules to analyze the optical signatures of coherent acoustic phonons in nanoparticles. This strategy enables us to better understand the implications of energetic changes induced by coherent phonons. Then, we apply this approach to systems that target coherent acoustic phonons as a route to modulate plasmon-exciton coupling and compare the results to theoretical calculations. Taken together, the described approach provides an intuitive, simple means of analyzing future systems and facilitates attempts to utilize, rather than simply observe, nanomaterial phonon modes.

Phase control of coherent acoustic phonons in gold bipyramids for optical memory and manipulating plasmon–exciton coupling

Journal Article Kirschner, Matthew S. ; Lin, Xiao-Min ; Chen, Lin X. ; ... - Applied Physics Letters

Recent efforts have targeted manipulation of nanomaterial vibrational modes in applications such as chemical/mass sensing, optical switching, and phonon-driven photochemistry. While impulsive photoexcitation can generate coherent phonons, multiple excitation pulses offer the prospect of control and manipulation of coherent phonon modes for functions of optical memory and logic. In this work, we use such an approach to inject an arbitrary coherent phonon phase into a colloidal ensemble of highly monodisperse gold bipyramids. We then demonstrate that this technique can be applied to a system that exhibits plasmon-exciton coupling to further manipulate the hybridization of the system. This ability to manipulatemore »« less

Phonon-Driven Oscillatory Plasmonic Excitonic Nanomaterials

Journal Article Kirschner, Matthew S. ; Ding, Wendu ; Li, Yuxiu ; ... - Nano Letters

In this study, we demonstrate that coherent acoustic phonons derived from plasmonic nanoparticles can modulate electronic interactions with proximal excitonic molecular species. A series of gold bipyramids with systematically varied aspect ratios and corresponding localized surface plasmon resonance energies, functionalized with a J-aggregated thiacarbocyanine dye molecule, produce two hybridized states that exhibit clear anti-crossing behavior with a Rabi splitting energy of 120 meV. In metal nanoparticles, photoexcitation generates coherent acoustic phonons that cause oscillations in the plasmon resonance energy. In the coupled system, these photo-generated oscillations alter the metal nanoparticle’s energetic contribution to the hybridized system and, as a result,more »« less

Accelerating Biomimetic Solar - Energy Harvesting: Mapping the Interaction Landscape of Plasmonic-Excitonic Hybrid Nanosystems (Final Report)

Technical Report Eisele, Dorthe M.

In general, excitonic and plasmonic nanoscale materials in close proximity show high potential for significant breakthroughs in energy related materials research. The interactions between these two kinds of materials result in coupled optical transitions (plexcitons), distinct from those of both the individual exciton and plasmon as well as from those of the sum of their constituents (synergistic effects). By linking together materials-research and physical-research approaches, this project contributes to a concerted approach on nanomaterials energy research. The project’s overall goal is to accelerate the development of well-defined plexcitonic model systems consisting of carefully engineered plasmonic and excitonic nanomaterial— essential formore »« less

Size-Dependent Coherent-Phonon Plasmon Modulation and Deformation Characterization in Gold Bipyramids and Nanojavelins

Journal Article Kirschner, Matthew S. ; Lethiec, Clotilde M. ; Lin, Xiao-Min ; ... - ACS Photonics

Localized surface plasmon resonances (LSPRs) arising from metallic nanoparticles offer an array of prospective applications that range from chemical sensing to biotherapies. Bipyramidal particles exhibit particularly narrow ensemble LSPR resonances that reflect small dispersity of size and shape but until recently were only synthetically accessible over a limited range of sizes with corresponding aspect ratios. Narrow size dispersion offers the opportunity to examine ensemble dynamical phenomena such as coherent phonons that induce periodic oscillations of the LSPR energy. Here, we characterize transient optical behavior of a large range of gold bipyramid sizes, as well as higher aspect ratio nanojavelin ensemblesmore »« less

Optical and Physical Probing of Thermal Processes in Semiconductor and Plasmonic Nanocrystals

Journal Article Diroll, Benjamin T. ; Kirschner, Matthew S. ; Guo, Peijun ; ... - Annual Review of Physical Chemistry

This article reviews thermal properties of semiconductor and emergent plasmonic nanomaterials with a focus on mechanisms through which hot carriers and phonons are produced and dissipated, as well as the related impact on optoelectronic properties. Equilibrium elevated temperatures, of particular relevance to implementation of nanomaterials in devices, affect absorptive and radiative transitions as well as emission efficiency that can present reversible and irreversible changes with temperature. In noble metal or doped semiconductor/insulator nanomaterials, hot carriers and lattice heating can substantially influence localized surface plasmon resonances and yield large, ultrafast changes in transmission, or strongly oscillatory coherences.
