Texte intégralQuantum dots are very promising in the field of quantum information which requires the use of single photons for quantum cryptography or quantum calculation. Thus, it is necessary to understand the physic of single InAs/GaAs and InAs/InP quantul dots emitting in 1. 3 to 1. 5 micrometer spectral range, wavelengths adapted for the transmission through optical fibres. In this thesis, we studied the exciton-biexciton complex, the fine structure splitting, the impact of the temperature and charged excitons in single quantum dots. We observed the dependence of the biexciton binding energy and of the fine structure splitting as a function of the InAs/InP quantum dot size. Moreover, the studies as a function of the temperature showed that the linewidth of the exciton recombination is in the meV range nitrogen temperature and in the 10-15 me V range at room temperature for the InAs/GaAs dots

Texte intégralThe present work focus on the characterization of the structural and photoluminescence properties of a series of organic-inorganic hybrids. The matrix of these materials includes urea crosslinks between a siliceous backbone and an organic chain (polyether, alkylene and bipyridine based). The origin and energy transfer processes behind the emission features was studied for the polyether-based organic/inorganic hybrids lacking metal activator and incorporating Eu3+ (that were well characterized in previous works) in order to have a theoretical scheme that will be useful in guiding the interpretation of experimental data and in the design of new organic/inorganic hybrids. The effect of the morphology on the photoluminescence features of hybrids was also studied; alkyl-based hybrids with different morphologies were obtained from the same precursor (designated P12) using acidic or nucleophilic catalysis, in the presence of Eu3+, giving lamellar and amorphous hybrids lamellar materials and the respective structural and luminescence features compared. Two amorphous bipyridine-based materials were synthesized exhibiting high stability over time and high emission quantum yield values (0. 18±0. 02 and 0. 22±0. 02) for excitation in the long UV/blue regions using a commercial light emitting diode (LED). These bipyridine-based hybrids incorporating Eu3+, Gd3+, and/or Tb3+ ions were also synthesized and the key role played by the light emitted by the hybrid host in the luminescence of the corresponding Ln3+-based hybrids was demonstrated

Texte intégralSilicon is known as a poor light emitter due to its indirect band gap. Various strategies have been developed to overcome its poor emission efficiency since it is the material of choice for photonics. In this manuscript are detailed the elaboration and characterization of original silicon-based materials in order to propose alternatives solutions to improve Si light emission properties. This work is divided in 4 parts with a first one describing the state of the art of light emission in Si and the basics of recombination mechanisms in Si. A second part focuses on the elaboration and study of electroluminescent devices based on bulk Si with a buried dislocation network at a PN junction obtained by wafer bonding. The light emission near 1.1 and 1.5 µm (1.1 and 0.8 eV) is attributed to the recombination of carriers on trap states induced by boron and oxide precipitates in the vicinity of dislocations (E^phonon_Bore near 1.1eV and Dp~0.8eV) and defects traps at the intersection of the square network of screw dislocations (D1~0.8eV). In a third part is showed the elaboration and the optical properties of Er3+ ions coupled with Si nanostructures in Si-Rich Silicon Oxide (SRO) thin films obtained by co-evaporation of SiO and Er. We demonstrate the efficient indirect excitation of Er at 1.5 µm with high effective cross sections between 2x10-16 cm2 and 5x10-15 cm2 as a function of the excitation flux and the elaboration parameters. The main result is the drastic decrease of the number of Er3+ emitting ions coupled to Si with the annealing temperature. EXAFS experiments revealed that this behavior is correlated with the evolution of the local chemical order around Er atoms. In a last part is presented the elaboration of Si nanostructures based on core-shell Si/SiO2 nanowires. These core-shell structures are obtained by three different methods. Core-shell nanowires obtained by oxide deposition on the surface of CVD Au-catalyzed Si nanowires exhibit an efficient room temperature emission around 500 nm due to the recombination of photo generated carriers in defects states in the oxide layer and at the Si/SiO2 interface. The collected PL intensity is more than one order of magnitude higher than similar SiO2 thin films deposited on Si substrates. Moreover, the passivation of CVD-growth Si nanowires by a thermal oxidation procedure allows neutralizing the surface states which are predominant in such structures. As a result, the measurement of surface recombination velocities seems to indicate that such passivated nanowires present similar volume electronic properties than standard microelectronic bulk Si. Finally, a new method for the elaboration of in situ core-shell Si/SiO2 nanowires based on the evaporation of a solid SiO source with Au and Cu as catalysts is presented. The Au-catalyzed growth occurs in the VLS mode (Vapor-Liquid-Solid like in CVD-growth) leading to the growth of nanowires with a crystalline Si core surrounded by an amorphous oxide shell. But Cu-catalyzed nanowires growth seems to appear preferentially at lower temperatures in the VSS (Vapour-Solid-Solid) mode explaining why these nanowiress exhibit a high density of crystalline defects in the Si core compared to Au-catalyzed wires

Texte intégralWe investigate the presence of dynamical heterogeneities in supercooled water with molecular dynamics simulation. The new water model TIP5P proposed by Mahoney and Jorgensen which reproduces well water properties is used. We validate our simulation by a compartive study of our results and those obtained in experiments. Thereafter, We show the existence of dynamic heterogeneities in supercooled water. We then studied dynamic aggregations of the molecules of different mobilities and find a string-like dynamics for the most mobile molecules and also dynamical aggregation of the least mobile molecules. The two kinds of dynamical aggregation appear however to be very different. We observes two different times characteristic associated to the two types of heterogeneities. Many sizes of boxes are used for simulations and we show the finite size effect on static and dynamic properties of supercooled water. In the second part of this work, we studied the properties of the charge carriers in mesoscopic structures type OD, 1D, 3D. Using Feynman variational method we carry out theoretical calculations of the characteristics (energy and mass) of the (bi)polaron in nanostructures. We obtain the relation between these characteristics, radius, anisotropy and the Fröhlich electron-phonon coupling constant. By numerical optimization, we obtained that the ground state energy and mass of (bi)polaron increase with the coupling constant and confinement frequency. We developed a theory of photoluminescence assisted by phonons in a spherical nano crystal for various mechanisms of interaction between the electrons and the phonons
