Abstract
(EN)
A magnetic quantum dot. The magnetic quantum dot comprises a magnetic nanoparticle core (10), a quantum dot layer (20) coating the outer surface of the magnetic nanoparticle core, and an organic shell layer (30) coating the outer surface of the quantum dot layer. A preparation method for magnetic quantum dots comprises: adding quantum dots and magnetic nanoparticles into a surfactant-containing aqueous solution to obtain a micellar solution in which quantum dot layers (20) coat magnetic nanoparticle cores (10); and then mixing the micellar solution with organic shell layer (30) materials to obtain magnetic quantum dots. Magnetic quantum dots are prepared into magnetic ink of different colors according to requirements and are mixed with common ink and injected into an ink cartridge. The ink cartridge comprises a body, a nozzle, and an electromagnetic field generator provided between the body and the nozzle. By controlling the strength of the electromagnetic field, the content of the magnetic ink in the jetted ink is controlled, and the components of the jetted ink are adjusted, improving the printing efficiency and the utilization rate of the ink cartridge.

L'invention concerne un point quantique magnétique. Le point quantique magnétique selon l'invention comprend un noyau de nanoparticules magnétiques (10), une couche de points quantiques (20) revêtant la surface externe du noyau de nanoparticules magnétiques, ainsi qu'une couche d'enveloppe organique (30) revêtant la surface externe de la couche de points quantiques. L'invention concerne également un procédé de préparation de points quantiques magnétiques, consistant : à ajouter des points quantiques et des nanoparticules magnétiques dans une solution aqueuse contenant un tensioactif afin d'obtenir une solution micellaire dans laquelle des couches de points quantiques (20) revêtent des noyaux de nanoparticules magnétiques (10) ; puis à mélanger la solution micellaire avec des matériaux de couche d'enveloppe organique (30) afin d'obtenir des points quantiques magnétiques. Les points quantiques magnétiques selon l'invention sont préparés sous la forme d'encre magnétique de différentes couleurs, en fonction des besoins, et sont mélangés à de l'encre commune et injectés dans une cartouche d'encre. La cartouche d'encre comprend un corps, une buse et un générateur de champ électromagnétique disposé entre le corps et la buse. La régulation de l'intensité du champ électromagnétique permet de réguler la teneur en encre magnétique de l'encre éjectée et d'ajuster les composants de l'encre éjectée, ce qui améliore l'efficacité d'impression et le taux d'utilisation de la cartouche d'encre.
