Abstract
Metal quantum dots are produced from a solution of the metal salt when the solution is passed through an electrostatic capillary nozzle (3) into a chamber (7). The nozzle (3) produces an aerosol of droplets (4) of the solution which is then irradiated using laser light (8). The solution evaporates from the droplets to form quantum dots of the metal element on a substrate 5 in the chamber 7.
Claims13
A method of producing metal quantum dots, which method comprises:
- (1) providing a solution in an evaporable solvent of the metal in chemically combined form,
- (2) passing the solution through an electrostatic capillary nozzle to form droplets of the solution in a chamber,
- (3) irradiation of the droplets within the chamber with photons and
- (4) removing the evaporable solvent from the droplets to form metal or metal oxide particles.
