In order to clarify the nanoparticles formation process of the metal sputtering onto ionic liquid, which is the facile method to prepare metal nanoparticles, the vacuum-liquid interface was captured by a camcorder while conducting gold sputtering. Because of intense color of Au clusters, move of Au clusters by convection of ionic liquid was clearly observed. The convection is a dominant factor in a transport of the resulting Au nanoparticles from the surface to interior of the ionic liquid.
