Abstract

The invention discloses a method and a device for quantum dot synthesis under auxiliary drive of a capillary force. The device comprises a precursor liquid storage device (1), a magnetic pump (2), a flow meter (3), a micro-channel reactor (4) and a quantum dot collector (5). The method includes: pumping quantum dot precursor liquid into the micro-channel reactor (4), and enabling the precursor liquid to diffuse into capillary microgrooves (8) to react under capillary force drive of a first capillary liquid suction core (7) in an inlet area; enabling obtained quantum dot solution to flow out of the micro-channel reactor (4) under capillary force drive of a second capillary liquid suction core (9) in an outlet area and flow into a quantum dot collector (5) through a guide tube, so that the quantum dot solution is obtained. The method and the device for quantum dot synthesis under auxiliary drive of the capillary force have advantages that continuous synthesis of quantum dots under low-power or even powerless conditions is realized, uniformity of the quantum dots is effectively improved, and the synthesis method is simple in operation, low in process cost and beneficial for industrial production of the quantum dots.
