The research axe " Optical and Thermophysical
Properties" links two teams among the seven developed at the
CRMHT.
The research aim of this group is mainly oriented to the study of the optical
properties with the temperature. We are interested by oxide materials (from
single crystals to ceramics and glasses in their solid and liquid states), but
the studies are extended to other families such as
nitrides, carbides, materials for high temperature applications. The microscopic
approach is performed on different spectroscopies, infrared, Raman, Brillouin.
To take into account the links between the transport properties in the
solids and in the liquids, macroscopic characterization of the ionic mobility,
and the measurement of the thermal emission of semi-transparent materials,
dominated by the same mobility at high temperature, we shared our activity into
two research topics strongly linked.
