Claims
- 1. A process for producing nano-scale particles comprising the steps of:
- a. placing a substrate on a rotatable specimen holder that is inside a reactive chamber, where said specimen holder is rotatable by a drive source;
- b. filling said reactive chamber with a liquid precursor solution to a level above said substrate;
- c. rotating said specimen holder and therefore said substrate by engaging said drive source;
- d. irradiating said rotating substrate and said liquid precursor solution with a laser beam thereby producing said nano-scale particles; and
- e. separating the particles from the irradiated liquid precursor solution.
- 2. The process as claimed in claim 1, wherein said particles are selected from the group consisting of silver, gold, platinum, palladium nickel, tin, iron, copper, zirconium, vanadium and oxides and alloys thereof.
- 3. The process as claimed in claim 2, wherein said specimen holder and said substrate are rotated at a range from 0 to 1000 revolutions per minute.
- 4. The process as claimed in claim 3, wherein said substrate and liquid precursor solution are irradiated for a time period of 3 to 7 minutes.
- 5. The process as claimed in claim 1 wherein the precursor solution additionally contains a surfactant.
- 6. The process as claimed in claim 1, wherein the precursor solution comprises a metal nitrate.
