Quantum dots of a metal or metal compound are made by a method of providing a solution in an evaporable solvent at a predetermined concentration of a chosen metal and forming droplets of the solution of a substantially uniform predetermined size. The droplets are thereafter brought into contact with a gas phase reagent thereby forming the metal or metal compound quantum dots desired. The solvent may be removed before, during or after the contacting of the droplets with the gas phase reagent. The metal or metal compound quantum dots so formed are deposited on a substrate. The quantum dots may be contained within a polymer as a film. By control of the concentration of the solution and the size of the droplets the size of the quantum dots may be closely controlled.
A method of making quantum dot particles of substantially uniform size of a metal or metal compound, which method comprises providing a solution in an evaporable solvent at a predetermined dilution of the metal in chemically combined form, forming the solution into droplets of substantially uniform predetermined size, contacting and reacting the droplets with a gas-phase reagent as the droplets move through the gas-phase reagent thereby forming the metal or metal compound, removing the evaporable solvent from the droplets whereby each droplet forms a respective quantum dot particle of the metal or metal compound and collecting the quantum dot particles on a substrate.
A method of making nanometric particles of substantially uniform size of a metal or metal compound, which method comprises providing a solution in an evaporable solvent at a predetermined dilution of the metal in chemically combined form, forming the solution into droplets of substantially uniform predetermined size, contacting and reacting the droplets with a gas-phase reagent as the droplets move through the gas-phase reagent thereby forming the metal or metal compound, and removing the evaporable solvent from the droplets whereby each droplet forms a respective nanometric particle of the metal or metal compound.
