Abstract
(EN) Disclosed is a light-emitting material including: a substrate that includes a metal oxide and/or a metal sulfide; two or more linker groups bonded to the substrate; a phosphine oxide ligand bonded to each of the linker groups, each phosphine oxide ligand having a single phosphine oxide group; and a rare earth ion. A rare earth complex is formed by a single rare earth ion and two or more phosphine oxide ligands.
(FR) L'invention concerne un matériau électroluminescent comprenant : un substrat qui comprend un oxyde métallique et/ou un sulfure métallique ; au moins deux groupes de liaison liés au substrat ; un ligand d'oxyde de phosphine lié à chacun des groupes de liaison, chaque ligand d'oxyde de phosphine présentant un groupe d'oxyde de phosphine unique ; et un ion de terre rare. Un complexe de terre rare est formé par un seul ion de terre rare et au moins deux ligands d'oxyde de phosphine.
(JA) 金属酸化物又は金属硫化物のうち少なくとも一方を含む基材と、基材に結合した2以上のリンカー基と、及びそれぞれのリンカー基に結合した、1つのホスフィンオキシド基を有するホスフィンオキシド配位子と、希土類イオンとを含む発光材料が開示される。1つの希土類イオンと2以上のホスフィンオキシド配位子とで希土類錯体が形成されている。
