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.
