The candidate will be responsible for the synthesis of fluorescent nanocrystals (quantum dots) by colloidal means, their characterization and the development of new white light generating devices based on the use of textile materials made photoluminescent by association of QDs excited by laser diodes emitting in the violet range/blue.
The proposed work will be mainly dedicated to the development of new solvothermal synthesis methods to produce dispersible semiconductor nanocrystals in a monomeric matrix. The reaction conditions, stoichiometry, doping and the influence of the surface ligand on physical (photo)properties will be particularly studied, with special attention to the stability of these nanoparticles.
- synthesis of colloidal dispersions of QDs and surface functionalization.
- Characterization of the structural and electronic properties of the nanocrystals.
- dispersion of QDs in monomers.
- photopolymerisation of monomers and study of the optical properties of the films.
The candidate will need to have strong experience in the field of nanoparticle synthesis, characterization and functionalization.
- Nanocrystal synthesis methodology.
- inorganic synthesis and colloid chemistry.
- characterization of nanoparticles, in particular by optical means.
The Reaction and Process Engineering Laboratory (UMR 7274) is a joint unit of the CNRS and the University of Lorraine created on January 1, 2010 and based in Nancy. Its general scientific objective concerns the study of processes taken as a whole and their complexity. The LRGP develops the scientific and technological knowledge necessary for the design, study, conduct and optimization of complex processes of physico-chemical and biological transformation, matter and energy. The unit has more than 300 people, with nearly 20 CNRS researchers, 80 research teachers, 45 technical and administrative staff and 180 non-permanent staff (contract researchers, 85 PhD students, post-doctoral students, masters, trainees).
