Abstract
A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.
Claims8
A method for synthesizing nanoparticles, comprising:
- preparing one or more constituent elements at a temperature below 100° C., wherein the constituent elements include ionic liquids that enhance formation rates of the nanoparticles;
- heating the prepared constituent elements using microwave irradiation to an elevated temperature at a rate of 30° C./min or higher, in order to create a reaction mixture;
- stabilizing the reaction mixture at the elevated temperature;
- and
- cooling the stabilized reaction mixture to a reduced temperature at a rate of 80° C./min or higher, so that the nanoparticles are synthesized.
