PhD Thesis

Directed and enhanced photoluminescence of quantum nanoemitters using all-dielectric nanoantennas

• Multidisciplinary topic based on the expertise of two laboratories from Toulouse.

• Funding by Université Paul Sabatier – Région Occitanie for 3 years 2018-2021 (ongoing granting)

Introduction and context - High-index dielectric nanostructures sustain electric and magnetic resonances in the visible. These resonances make possible a strong localization and enhancement of the field in the vicinity of the nanostructures, leading to a strong modification of the photonic local density of states. Consequently, the light emission by quantum emitters positioned in the near field of these structures can be controlled (enhancement, directivity, etc). In addition, the interferences between these resonances of low or high order allow for the manipulation of specific properties of light like the directivity of the scattered light in the far field. This topic is a growing field of research which is now challenging Plasmonics.

Key words-single photon sources, colored centers, nanodiamond, quantum dots, dielectric nanostructures, directed assembling, nanoxerography, Atomic Force Microscopy (AFM), time-resolved optical microscopy, photon correlation, numerical simulation of optical properties.

1D metal nanostructures: growth mechanism and controlled organization for tailored functional materials

The synthesis of anisotropic metal nanoparticles and nanostructures is developed at LPCNO for different applications in the fields of flexible electronics, permanent magnets or catalysis. The optimization of the targeted properties requires both a better understanding of the growth mechanism for a better control of the particle size, shape and surface chemistry, and tailored organizations in solution or as functional nanomaterials.
