Title (EN) PROCESS FOR FORMULATING QUANTUM DOTS
(FR) PROCÉDÉ DE FORMULATION DE POINTS QUANTIQUES
Abstract:
(EN) The present invention relates to a process for formulating quantum dots for the use as luminescent pigment in lighting devices such as light-emitting diodes, functional films, coatings, or photo resists. In particular, the present invention relates to a process for producing encapsulated quantum dots comprising (a) agglomerating quantum dots to form quantum dot agglomerates, and forming a shell around the quantum dot agglomerates by performing 3 to 80 cycles of an atomic layer deposition process while the quantum dot agglomerates are in motion.
(FR) La présente invention concerne un procédé permettant de formuler des points quantiques destinés à être utilisés en tant que pigment luminescent dans des dispositifs d'éclairage tels que des diodes électroluminescentes, des films fonctionnels, des revêtements ou des photo-réserves. En particulier, la présente invention concerne un procédé de production de points quantiques encapsulés consistant à (a) agglomérer des points quantiques pour former des agglomérats de points quantiques, et à former une écorce autour des agglomérats de points quantiques en effectuant de 3 à 80 cycles d'un procédé de dépôt de couche atomique tandis que les agglomérats de points quantiques sont en mouvement.
