Abstract:
(EN) The present invention relates to a color conversion layer (4) comprising at least one light emitting material (7) comprising at least one composite particle (1) surrounded partially or totally by at least one surrounding medium (71); wherein said light emitting material (7) is configured to emit light in response to an excitation and the at least one composite particle (1) comprises a plurality of nanoparticles encapsulated in an inorganic material; and wherein said inorganic material has a difference of refractive index compared to the at least one surrounding medium (71) superior or equal to 0.02 at 450 nm. The present invention also relates to an illumination source and a display apparatus.
(FR) La présente invention concerne une couche de conversion de couleur (4) comprenant au moins un matériau électroluminescent (7) comprenant au moins une particule composite (1) entourée partiellement ou totalement par au moins un milieu environnant (71) ; ledit matériau électroluminescent (7) étant conçu pour émettre de la lumière en réponse à une excitation et ladite particule composite (1) comprenant une pluralité de nanoparticules encapsulées dans un matériau inorganique ; et ledit matériau inorganique ayant une différence d'indice de réfraction par rapport audit milieu environnant (71) supérieur ou égal à 0,02 à 450 nm. La présente invention concerne également une source d'éclairage et un appareil d'affichage.
