Precise control of the materials properties implies mastering the atomic-, nano-, meso- and macro-scales. In the case of nanoparticles, this means tunability of the crystal structure, the particle size and morphology, and the order between the numerous particles into the material. Reaching such a control, especially for compounds of complex compositions, calls for the development of alternative production methods. This research axis aims at exploring new synthesis routes focused on the use of molecular sources and low environmental footprint processes: Chimie Douce aqueous precipitation, colloidal synthesis in molten salts, and combination of the sol-gel process and carbothermal reduction.
