Synthesis and sol-gel assembly of nanophosphors

recent works made in our group on inorganic nanophosphors are briefly reviewed in this paper. We first present to synthesis of highly concentrated semiconductor quantum dot colloids allowing the extension of the well-known oxide sol process to chalcogenide compounds Secondly, we show the synthesis and the chemical functionalization of lanthanide-dopant insulator nanoparticles. In particular, the annealing process of these particles at high temperature leads to highly bright nanocrystal which can be used as biological luminescent labels or for integration in transparent luminescent coatings. Finally, we considered luminescent transition metal clusters, which combine the inorganic structure of nanoparticles with the monodispersity and the each functionalization of the organic molecules Emphasis is put on the original thermochromic luminescence properties of copper iodide clusters trapped in siloxane-based films.
