Повний текст джерелаNonlinear optics is well known to be a highly powerful tool to investigate the photonic properties of molecules, materials and nanostructures. Size and shape of noble metal nanoparticles (NMNPs) strongly influence their second-order nonlinear optical properties. In this PhD thesis, we propose a systematic investigation of the influence of the nanoparticle surface area on their first hyperpolarizability beta values. Powdery-silver nanoparticles (diameters 7 nm) and colloidal solutions on NMNPs with different composition, sizes and shapes have been synthesized, i.e. silver nanospheres (diameters 10 nm), gold nanospheres (diameters 3.0; 11.6; 15.8; 17.4; 20.0 and 43 nm), gold nanorods (aspect ratios 1.47; 1.63 and 2.30), silver nanorods (aspect ratios 5.0; 6.3; 7.5; 8.2 and 9.7), platinum nanoflowers (diameters 7.0; 8.0; 10.0; 14.0; 20.0 and 31.0 nm) and gold nanoprisms (edge length tuned from 47.5 to 112.3 nm). Harmonic light scattering (HLS) at 1064 nm is used to investigate the second harmonic generation from colloidal NMNPs, and to infer their first hyperpolarizability tensor beta. For the nanospheres and nanorods investigated in this work, we demonstrate that their beta values display a strong dependence with their surface area, which is the dominant parameter in the evolution of beta values. Otherwise, particle surface corrugation and shape irregularities of nanoflowers are responsible for exceptionally high beta values. Moreover, we report for the first time in the literature that the beta values of nanoprisms display not only a linear dependence with respect to the surface area, but are also sensitive to the sharpness of the triangle vertices

Повний текст джерелаDuring this thesis, we used a photochemical imaging approach developed at LNIO to study the optical near field of several kinds of metal nanoparticles. Our approach is based on the vectorial displacement of photo-sensitive molecules that undergo cycles of isomerization under optical excitation. These nanoparticles have been studied with a spatial resolution better than 15nm, ie λ/35. We studied in detail the optical near field of isolated gold nanocubes in terms of spatial confinement of electromagnetic hot spots. We have also introduced the new concept of “cold spots” which corresponds to the zones presenting no EM activity on the ridges of the nanocube. We demonstrated that cold spots are highly sensitive to polarization and can be much more confined than hot spots. Furthermore, we studied the electromagnetic coupling between neighboring silver nanoparticles. We experimentally demonstrated that it is possible to control the light localization from the far field domain in a plasmonic nanoantenna constituted of three aligned silver dots. Finally, we studied the effect of photo-induced molecular migration on the plasmonic response of metal nanoparticles based on white light illumination. It is shown that changes in effective refraction index of the surrounding media due to matter migration result in variations in the resonance wavelength

Повний текст джерелаThe usse of a pump-probe experimental setup allowed the study of different specific physical properties of different types of nano-objects. First, the selective study of an hybrid nanoparticles comosed of a CdS nanostick and a particle directly groxwn on the semiconductor part proved the existence of a transfer between the two part of the hybrid nanoparticle and showed that this phenomenon occurs in less than 15 femtosecondes. The study of optical propertie of gold nanoparticles with an extra charge due to the transfer showed that adding few electrons to a small gold nanoparticles leads to a red shift of the plasmon resonance. Secondly, measurment of the period of fundamental vibration modes of a bilayer nano-object (spheric or elongated) composed of a metallic core and a dielectric or metallic shell lead to information on the relative thickness of the layers and the contact quality between them. LAstly, the study of the characteristic time of electron-phonon interactions in metallic nanoparticles has proven that there are two different methods of measuring this characteristic time, and its investigation for small nanoparticles (less than 250 atoms) leads to the observation of a transition form a "bulk" to a molecular behaviour

Повний текст джерелаIn this work, we report the investigation of 1D and 2D photonic band gaps of a new class of materials using FDTD (Finite Domain Time Difference) method. These materials are obtained by doping glass with semiconductor or metal nanoparticles. The presence of the nano-objects in the silica permits to obtain a new composite material from which the optical properties are different from the starting host matrix. The originality of this new class of materials is in the possibility of obtaining tunable optical properties in several characteristic parameters of particles. The results of our simulations show that the characteristics of the diagrams of bands (number, width, central wavelength) of mirrors of Bragg (ZnS+glass) /glass and (Ag+glass) /glass, are adjustable according to the polarization, variation Δn, the form and the concentration of NP. No band gap was found for the 2D system constituted of ZnS particles disposed periodically in a host matrix with a square for TE and TM polarization modes. However in the case of hexagonal lattice, for the TE polarization mode, offer an interesting photonic band gaps. The example presented of the nanocavity gives us an idea of the photonic systems that we can obtain with these new materials. The study was enlarged to the modeling mirrors composed with metallic and semiconductor nanoparticles (NP) embedded in the dielectric matrix with introducing absorption of NP

Повний текст джерелаThis thesis is devoted to modeling of the optical properties of nanostructured dielectrics by metal particles. We interested in two aspects of the problem: the determination of effective index and field distribution of plasmon nanoparticles dispersed in such media. We have developed two numerical approaches. The first is devoted to the simulation of real and imaginary parts of the effective index of heterogeneous medium. In order to compare experience and theory, we have proposed an experimental approach to measure the effective refractive index of colloidal solutions containing metal or semiconductor nanospheres. The second aspect deals with the method of extraction of the field plasmon on the surface of metal nanosphere when it is excited by electromagnetic plane wave. The calculated effective index and field plasmon are done in function of characteristic parameters of nanoparticles and host matrix
