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.
Claims20
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 is connected to a first thermocouple configured for a first temperature;
- and
- a second coil positioned in serial communication with the first coil, wherein the second coil is in fluidic communication with the first coil and directly attached to the first coil, wherein the second coil is configured to grow the QDs from the QD seeds and is connected to a second thermocouple configured for a second temperature, wherein the second temperature is lower than the first temperature,
- wherein the first coil and the second coil are independent of one another.
