Abstract
Systems, methods, and devices are disclosed for producing quantum particles (e.g., quantum dots) having a uniform size by vaporization of molten precursor droplets. More particularly, the present technology produces quantum dots by melting or liquefying solid and substantially pure precursor materials followed by production of uniformly sized droplets of molten precursor by use of a droplet maker into a microwave generated plasma torch.
Claims1
A method of manufacturing a quantum dot having a core at least partially surrounded by a shell, the method comprising:
- melting a core precursor material to create a molten core precursor material;
- forming core precursor material droplets having controlled droplet size from the molten core precursor material;
- vaporizing the core precursor material droplets within plasma;
- forming quantum dot cores from the vaporized core precursor material droplets;
- melting a shell precursor material to create a molten shell precursor material;
- forming shell precursor material droplets of the molten shell precursor material;
- vaporizing shell precursor material droplets within plasma;
- and
- forming quantum dot shells on the quantum dot cores.
