Abstract

L'invention concerne un dispositif de synthèse de cœur de points quantiques, comprenant une région de réaction de formation de cœur, qui comprend au moins un tube de réaction en spirale. Une rainure de guidage, qui s'étend dans une direction opposée à la forme en spirale et qui permet à des réactifs injectés dans le tube de réaction de générer un effet de bullage par frottement, est formée sur la paroi interne du tube de réaction en spirale; une région de chauffage recouvre une section avant de la région de réaction de formation de cœur; une région de refroidissement recouvre une section arrière de la région de réaction; plusieurs ouvertures d'injection sont formées au niveau de l'extrémité avant de la région de réaction de formation de cœur; plusieurs ouvertures d'évacuation de seston sont formées au niveau de l'extrémité arrière de la région de réaction de formation de cœur; l'extrémité avant de la région de réaction de formation de cœur est reliée à un dispositif de mise sous pression. L'invention concerne également un dispositif de synthèse de cœur de points quantiques. Dans la présente invention, le dispositif de synthèse de cœur de points quantiques est simple en matière de structure et fiable; en formant une rainure de guidage sur le tube de réaction en spirale, les réactifs peuvent être mis sous agitation; le temps de passage des réactifs dans le tube de réaction en spirale peut être réglé en régulant le diamètre interne et la longueur du tube de réaction en spirale par rapport à différents types de cœurs à synthétiser, de sorte que des cœurs de haute qualité peuvent être obtenus.
