Description of the thesis topic

The HEMERALD (High Efficiency of Massive Emitting ceRAmic for the 1.7-2.7 μm LASER winDow) project proposes to develop new transparent ceramics as active gain materials for the 1.7-2.7 μm LASER window through the exploration of the loud oxides and niobium phase diagrams. Targeted cubic compounds (Garnet, Pyrochlore and Fluorite compounds) will be doped with rare earth elements at different molar substitution rates to evaluate their optical properties. Syntheses will be optimized in order to produce powder with suitable size, morphology and thermal behavior regarding their shaping as transparent ceramics. Several sintering process will be performed to reach a full densification of the object. The activity will be shared between ICMCB (Bordeaux) and IRCER (Limoges). Diploma: Master of chemistry, solid state science, materials engineering The student should have a solid background in solid chemistry and theoretical knowledge in characterization techniques (X-Ray diffraction, electronic microscopy, spectroscopy…). Interest and skills in the conception and use of experimental devices are suitable

Work Context

Founded in 1995, the lnstitute for Condensed Matter Chemistry of Bordeaux activities include both fundamental and applied research and focus on 3 domains : Solid State Chemistry, Materials Science and Molecular Science. ICMCB has extensive expertise in design, synthesis, shaping and characterisation of materials, with the goal to explore and optimise their functionalities. This wide scope and a large, complementary spectrum of methods available, generate fruitful synergies among our faculty (researchers, engineers and technical staff) - contributing to the outstanding reputation of the ICMCB.
