PCT No. PCT/GB94/02514 Sec. 371 Date Jun. 18, 1996 Sec. 102(e) Date Jun. 18, 1996 PCT Filed Nov. 15, 1994 PCT Pub. No. WO95/13891 PCT Pub. Date May 26, 1995Quantum 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. |
