Updated: 2 months ago
Job Type: FullTime
Deadline: 24 Oct 2022

A 3-year PhD scholarship in Organic Chemistry and Photophysical studies is available starting from January 1, 2023 or as soon as possible thereafter. The project will be carried out as a collaboration between the groups of Assoc Prof Katrine Qvortrup (Technical University of Denmark (DTU), Department of chemistry) and Prof Christophe Galland (EPFL, Switzerland, Laboratory of Quantum and Nano-Optics). The PhD-student will be enrolled at DTU and spend a minimum of 6 months at EPFL.

Gold nanoparticles (AuNPs) are the most widely used inorganic nanoparticles for nanostructure-based materials. The synthetic engineering of organic ligands on the AuNPs leads to almost endless possibilities for tuning material properties (e.g. optical, electrochemical, photothermal, electronic, etc.).

The PhD project will focus on the design, synthesis, and characterization of new types of Au-organic nanostructures with engineered and optimised metal-molecule interaction for applications in nano-plasmonics, nonlinear optics, molecular electronics chemical sensing, and photo-induced chemistry. Characterization will include the elucidation of structural and physical properties, optical response (Raman scattering, infrared absorption, etc.), electronic structure and charge transport – both at the ensemble and individual nanoparticle level. Many experiments will be performed at EPFL in Switzerland. The project will have significant impacts on the understanding of AuNP chemistry and hybrid Au-organic photo-physics, and will clarify the correlations between chemical and electronic structures and the ensuing nanostructure properties. Active dissemination of the obtained results in scientific articles and through participation in international conferences is an integral part of the thesis.
