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.

Nanocomposite material made of a polymer-matrix comprising PEO- containing polymers and salts of luminescent polyanionic metal clusters

This deals with a luminescent salt comprising a metal cluster anion and an organic cation, wherein the metal cluster anion comprises a metal cluster with at least two metal atoms, and ligands, the metal atoms being chosen from the group consisting of molybdenum, rhenium, tungsten, thallium, niobium, and mixtures thereof, wherein the organic cation comprises a cationic head substituted by at least one substituent including a polymerizable functional group. It also deals with a polymeric material comprising a polymer matrix which has polymerized with this luminescent salt.
