Abstract
Embodiments of the present disclosure provide for methods of making quantum dots (QDs) (passivated or unpassivated) using a continuous flow process, systems for making QDs using a continuous flow process, and the like. In one or more embodiments, the QDs produced using embodiments of the present disclosure can be used in solar photovoltaic cells, bio-imaging, IR emitters, or LEDs.
Claims22
A method of forming a quantum dot (QD), comprising:
- a) mixing a solution A with a solution B to form solution C;
- b) flowing solution C into a nucleating coil to produce QD seeds by nucleating solution C at a first temperature;
- and
- c) flowing solution C including the QD seeds into a growth coil to grow the QDs at a second temperature,
- wherein b) and c) are independently performed, and wherein the first temperature and the second temperature are different.

A system for making a quantum dot (QD), comprising:
- a mixing device for receiving solution A and solution B, wherein the mixing device is configured to mix solution A and solution B to form solution C;
- a first coil in fluidic communication with the mixing device, wherein the first coil is configured to form QD seeds from solution C via nucleation;
- and
- a second coil positioned in serial communication with the first coil, wherein the second coil is in fluidic communication with the first coil, wherein the second coil is configured to grow the QDs from the QD seeds, wherein the first coil and the second coil are independent of one another.
