In the optical domain, the latter dependence can be exploited to tune the plasmonic response of metal nanoparticles by controlling their surroundings, notably applying high pressures. To date, only a few optical absorption experiments have demonstrated this feasibility, on ensembles of metal nanoparticles in a diamond anvil cell. Here, we report a nontrivial combination between a spatial modulation spectroscopy microscope and an ultraflat diamond anvil cell, allowing us to quantitatively investigate the high-pressure optical extinction spectrum of an individual nano-object. A large tuning of the surface plasmon resonance of a gold nanobipyramid is experimentally demonstrated up to 10 GPa, in quantitative agreement with finite-element simulations and an analytical model disentangling the impact of metal and local environment dielectric modifications. High-pressure optical characterizations of single nanoparticles allow for the accurate investigation and modeling of size, strain, and environment effects on physical properties of nano-objects and also enable fine-tuned applications in nanocomposites, nanoelectromechanical systems, or nanosensing devices.</dcterms:abstract> <dc:creator>Del Fatti, Natalia</dc:creator> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2019-01-09T10:31:01Z</dcterms:available> <dcterms:issued>2018-10-09</dcterms:issued> <dc:creator>Maioli, Paolo</dc:creator> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/44472"/> <dc:contributor>Silva Santos, Silvio D.</dc:contributor> <dc:creator>Medeghini, Fabio</dc:creator> <dc:contributor>Crut, Aurélien</dc:contributor> </rdf:Description> </rdf:RDF>
