Nanocomposite Material Made of a Polymer-Matrix Comprising PEO-Containing Polymers and Salts of Luminescent Polyanionic Metal Clusters

摘要

The present invention concerns a solid nanocomposite material consisting of a polymer-matrix in which are dispersed alkali metal, hydronium or ammonium salts of polyanionic components,;wherein the polymer-matrix comprises at least a linear or branched polymer or copolymer containing one or several poly(ethylene oxide) (PEO) chains, said polymer or copolymer being optionally crosslinked and each PEO chain having at least 4 ethylene oxide monomer units.;The present invention relates also to a photonic, e.g. optoelectronic, device comprising such a nanocomposite material.;Such material and device can be used as phosphorescence emitter, for crop growth lighting or for generating singlet oxygen.
