Abstract
An apparatus for manufacturing a quantum dot is provided, the apparatus including a first supplying part that provides a cationic precursor, a second supplying part that provides an anionic precursor, a mixing part connected to the first supplying part and the second supplying part, and a reaction part including a reaction tube configured to receive a liquid mixture of the cationic precursor and the anionic precursor from the mixing part and a first microwave generator configured to provide a microwave that is transmitted through the reaction tube. Therefore, the apparatus may produce a quantum dot of multi-element compounds.

An apparatus for manufacturing a quantum dot, the apparatus comprising:
- a first supplying part configured to provide a cationic precursor;
- a second supplying part configured to provide an anionic precursor;
- a mixing part connected to the first supplying part and the second supplying part;
- and
- a reaction part comprising a reaction tube configured to receive a liquid mixture of the cationic precursor and the anionic precursor from the mixing part and a first microwave generator configured to provide a microwave that is transmitted through the reaction tube, the first microwave generator being on a first plane parallel to a second plane on which the reaction tube is on, and the first and second planes being perpendicular to a thickness direction of the first microwave generator, the thickness direction being parallel to the transmission direction of the microwave, and
- wherein an extension direction of the reaction tube is on the second plane.
A quantum dot manufacturing method, the method comprising:
- providing a cationic precursor from a first supplying part and an anionic precursor from a second supplying part, the first supplying part being separate from the second supplying part;
- mixing the cationic precursor and the anionic precursor in a mixing part;
- and
- supplying a liquid mixture of the cationic precursor and the anionic precursor to a reaction tube through which a microwave is transmitted and synthesizing a multi-element compound comprising at least one cationic element contained in the cationic precursor and at least one anion element contained in the anionic precursor by providing the microwave to the liquid mixture,
- wherein the microwave is transmitted from a microwave generator on a first plane parallel to a second plane on which the reaction tube is on, and the first and second planes are perpendicular to a thickness direction of the microwave generator, the thickness direction being parallel to the transmission direction of the microwave, and
- wherein an extension direction of the reaction tube is on the second plane.
