Abstract:It has been examined to disperse the Au nano-particles directly into liquid by replacing the solid substrate with low-vapor oil in a plasma sputtering apparatus. The dispersing particles in oil are much smaller than the conventional methods. Under low density of particles on oil, the intense absorbance peak is detected around 325nm and the shape and peak of absorption spectra don’t almost change following time, and the size of Au particles is steady. With higher density, the absorbance peak is stronger and shi… Show more
