Desk-top Metal Nanoparticles Synthesis System

This is an experimental apparatus to be used in research and development to form metal nanoparticles in gas phases. This experimental device is suitable for research and development of materials with new properties such as quantum effects and luminescence properties of nanoparticles in nano-sizes.

Metals such as Au, Ag, Cu, Al, Ni, Co, Si, etc. is heated and vaporized in an inert gas. The collision between the metal vapor and inert gas cools the metal vapor, so that metal nanoparticles of 10-30 nm in diameter are formed in the gas phase. A sharp size distribution of nanoparticles can be achieved. The nanoparticles can be directly deposited on a substrate located above the crucible.

In most cases, metal nanoparticles always show black color due to the plasmon effect; gold nanoparticles do not show gold color but black color.

It is well known that Au nanoparticles have a good catalyst effect and also are used in the biosensors. Ni, Co, or Fe nanoparticles show superparamagnetic effect. Si nanoparticles show EL effect.

This apparatus will be suitable to laboratory experiments on finding new functioned materials based on quantum effect.
