Magnetic and Fluorescent Hybrid Silica Nanoparticles Based on the Co-Encapsulation of γ-Fe2O3 Nanocristals and [Mo6Br14]2- Luminescent Nanosized Clusters by Water-in-Oil Microemulsion
Résumé
The design, synthesis and characterization of magnetic-luminescent nanoparticles is now more and more studied since the last decade. However, optimizing the design of such materials requires a deep understanding of their physico-chemical properties. In this paper are reported extended investigations on luminescent and magnetic [Mo6Br14-γ-Fe2O3]@SiO2 nanoparticles prepared by a colloid-water-in-oil microemulsion technique. The Cs2[Mo6Br14] cluster compound is used as red-NIR phosphor and is prepared by solid state chemistry. We bring here new insights into the structure of such Nps and its interplay with their optical or magnetic properties.
