The MIOPS group is a multidisciplinary team made up of chemists and physicists, experimentalists and theoreticians. Our objectives are the synthesis and/or the characterization of materials with optical, optoelectronic or magnetic properties. Investigations are systematically carried out with a concern for rationalization, the determination of the physical parameters (e.g. crystalline structure) and chemical (e.g. composition) that govern a phenomenon being a requisite to the final optimization of the properties of a material.
The group's activities can be divided into three main topics, "Oxides for optoelectronics and magnetism", "Chalcogenides: crystallochemistry and photovoltaics", and "Photoactivable hybrid materials". Studies works are achieved in a basic framework or with industrial partnerships.
Our fields of expertise are:
- the synthesis of new inorganic and hybrid organic-inorganic materials (ceramic or soft chemistry),
- the structural characterization of crystallized materials and glass-ceramics (structural determination on powders or single crystals, non-harmonicity, crystallography in resonant conditions, PDF analyzes, amorphous quantification, etc.),
- the determination of the optical properties of synthetic materials and gemstones (optical absorption, steady-state luminescence, time-resolved photoluminescence, Raman spectroscopy),
- the characterization of the magnetic properties of solids and the identification of the topology of the interactions,
- the study of chemical bonding via band structure calculations, and the determination of the resulting optical properties (complex refractive index, absorption and emission mechanisms, simulation of the luminescence spectrum, impact of defects on properties, ...),
- the manufacture of thin film photovoltaic devices, their structural and optoelectronic characterizations.
