“…The explanation of this behavior lies instead on the fact that the opposite faces of the prism do couple, leading to an aspect ratio-dependent redshift [3]. The plasmon modes are then standing waves, just like in optical nanoantennas [4][5][6]. In this example, varying a global parameter, the aspect ratio, affects the local behavior of LSPs (e.g., the energy of the modes, the intensity of which peaks very locally).…”

Abstract. We report on spatially resolved electron energy-loss spectroscopy studies of optical modes in individual star-shaped gold nanoparticles. We studied different morphologies, ranging from a spheroid to well-developed nanostars. For each shape, essentially two groups of modes are appearing: the first one is localized around the core of the nanostars and has an energy slightly less than the quasi-static dipolar mode of a gold sphere (about 2.2 eV); in the second group, the modes are localized at the end of the nanostar tips, with varying energies depending on the geometry of each tip and with energy down to 1.2 eV. The localization of the tip modes is interpreted with the help of boundary element methods simulations.

“…In the experiments reported in this paper, we estimate the peak intensity incident on the sample to be on the order of 5*10 9 W/cm 2 . Compared to previous PEEM studies using 800 nm light, this intensity is in the high part of the reported ranges [11][12][13], which is expected due to the lower photon energy. The laser beam is s-polarized, i.e.…”

“…Although being subdiffraction, their intrinsic resolution is poorer than NSOM. Alternatively, there exist analysis techniques involving electrons as probes, as it is the case for cathode luminescence imaging [96], electron energy-loss spectroscopy (EELS) [63] and photoemission electron microscopy (PEEM) [27], which offer high spatial resolution but require vacuum environments. The local electromagnetic characterization of plamonic nanostructures in water-based systems, present in many emerging microfluidics studies, is therefore inaccessible to electronic microscopy.…”

iii Dans un cadre plus personnel, je remercie mes supercopines du labo: Emilie, Daria, Camille et Anne. Nos activités multiples en dehors du labo ont adouci les coups intrinsèquesà la thèse: des brunchs, des ateliers cuisine, des sessions de PPG et zumba, la piscine, de nombreuses soirées. . . Et bien sûr je remercie aussi mes copains masculins, toujours plus nombreux dans notre domaine, avec lesquels nous avons aussi partagé des très bons moments aussi bienà l'intérieur qu'à l'extérieur du labo: Baptiste, Olivier, Pierre, Nico et Marc. La plupart d'entre eux travaillent et vivent déjà ailleurs; le reste sont, comme moi, en train de dire au revoirà uneépoque importante. Mais mon départ me fait d'autant plus peine car j'ai aussi croisé des gens top sur la fin de cette thèse dont la plupart sont toujoursà Langevin. Heureusement, je suis sûre de revoir François, Fish, Mai, Clément, Nikos, Gautier, Jerôme et Marion sur les pistes de danse! Enfin, je remercie ma famille ainsi que ma famille politique pour leur soutien inconditionnel. Malgré la distance, ils sont restés très près de moi dans les moments les plus importants ces trois dernières années. Un sincère merci aussià mes copains catalans pour leur soutient, compréhension et fidélité de là où ils se trouvent. Cette réussite est aussi grâceà eux et je les porte dans mon coeur partout où je vais. iv AbstractIn this thesis work, we present a novel stochastic microscopy technique based on Digital Holography for the 3D mapping of optical intensity distributions. We show that this far-field, wide-field, 3D microscopy can be turned into both a superresolution and a nearfield imaging technique. To do so, we use metallic nanoparticles undergoing Brownian motion as stochastic local field probes that we localize in three-dimensions in order to overcome the diffraction limit. The random motion of the particles allows for a complete exploration of the sample. Beyond simple localization, the gold markers can actually be envisaged as extremely local electromagnetic field probes, able to scatter light into the far-field. The technique we propose here is therefore a combination of the concepts of superlocalization and NSOM microscopies. The possibilities of the technique are illustrated through the 3D optical mapping of an evanescent and a propagative wave.Fast computation methods allow us to localize hundreds of particles per minute with accuracies as good as 3 × 3 × 10 nm 3 for immobilized particles. In addition to optical intensity mapping, we show a particular application in electrochemistry, by coupling our high resolution images with electrochemical oxidation measurements on silver nanoparticles in solution at the vicinity of an electrode.Our results pave the way for a new subwavelength imaging technique, well adapted to optical characterization in water-based systems (such as in emerging microfluidics studies), which are mostly inaccessible to electron microscopy or local probe microscopies.
