Abstract

An apparatus for producing nanoparticles includes a vessel, a target, and a laser generating device. The vessel has an inlet and an outlet. The target is configured on a bottom of the vessel and disposed below the inlet. The produced nanoparticles flow continuously from the outlet with the produced solution and the protective solution can also be supplied into the vessel continuously from the inlet during production so as to mass-produce nanoparticles in a continuous and high efficient manner.

Claims

1. An apparatus for producing nanoparticles, comprising:

a vessel for containing a solution of surfactant, the vessel having an inlet and an outlet;

a target disposed below the inlet in the vessel; and

a laser generating device for applying a laser beam to the target.

2. The apparatus as described in claim 1, further comprising an ultrasonic device configured for dispersing the nanoparticles in the solution.

3. The apparatus as described in claim 1, wherein the target is comprised of a material selected from the group consisting of carbon, metal carbide, metal and metal alloy.

4. The apparatus as described in claim 3, wherein the target is comprised of a material selected from the group consisting of copper, silver, gold and any combination alloy thereof.

5. The apparatus as described in claim 1, wherein the laser generating device is selected from the group consisting of a gas laser, a liquid laser, a solid-state laser, and a semiconductor laser.

6. The apparatus as described in claim 1, wherein the outlet is configured to be lower than a top surface of the target.

7. The apparatus as described in claim 1, wherein the vessel is placed at an angle θ

with respect to horizontal, and the angle θ

satisfies the following formulation;
