Cr-doped Al 2 O 3 –YAG binary and Al 2 O 3 –YAG–ZrO 2 ternary eutectic materials crystallized by the micro pulling down ...
Cr-doped Al2O3-YAG and Al2O3-YAG-ZrO2 eutectic ceramics rods of 3 mm in diameter were solidified from the melt by a micro-pulling down (& mu;-PD) technique. The Cr dopant affects the microstructure, morphology, and lattice parameters of the as-grown eutectics. As a function of the dopant, the coloration, morphology, microstructure, and luminescence...

Photophysical Properties of Silver Clusters in Faujasite Zeolites: Does the Crystal Size Matter?
Electrostatic interactions between the zeolite cavity and confined noble-metal nanoparticles govern the photophysical properties of these materials. A better understanding of these interactions can afford new perspectives in optoelectronics applications. We investigated this interplay by revealing the peculiar photophysical properties of Ag cluster...
Caractérisation des champs électromagnétiques des systèmes rayonnants par thermo-fluorescence
La mesure du champ électromagnétique émis par diverses sources (antenne, radar) permet leur caractérisation et est utile en CEM (détection de fuites). Au-delà d'une mesure ponctuelle du champ proche, l'imagerie par thermographie permet une cartographie sur une surface, en un temps très court. La thermographie infrarouge a ainsi été développée par l...

Hyperspectral Imaging and Chemometrics for Authentication of Extra Virgin Olive Oil: A Comparative Approach with FTIR, U...
Limited information on monitoring adulteration in extra virgin olive oil (EVOO) by hyperspectral imaging (HSI) exists. This work presents a comparative study of chemometrics for the authentication and quantification of adulteration in EVOO with cheaper edible oils using GC-MS, HSI, FTIR, Raman and UV-Vis spectroscopies. The adulteration mixtures we...
Unexpected luminescence of non-conjugated biomass-based polymers: new approach in photothermal imaging
Population growth, depletion of world resources and persistent toxic chemical production underline the need to seek new smart materials from inexpensive, biodegradable, and renewable feedstocks. Hence, "metal-free" ring-opening copolymerization to convert biomass carvone-based monomers into non-conventional luminescent biopolymers is considered a s...
Periodic mesoporous organosilica based sensor for broad range mercury detection by simultaneous downshifting/upconversio...
Recent research in lanthanide materials has strongly contributed to the development of high-performance chemical sensors. However, the current reported high-responsive chemical sensors still have a limited detection range, restraining their further application. We developed lanthanide-based periodic mesoporous organosilica (LnPMO) hollow spheres wi...
