Abstract

Using an organic base, triethylamine, as the promoter, we successfully prepared highly concentrated and stablesuspensions of silver nanoparticles by chemical reduction of silver nitrate in formaldehyde with TSA as the stabilizer. The average size of the silver particles is less than 10 nm. The suspensions were stabilized by excess triethylamine. A50 wt%, stable suspension can be prepared. The suspensions of silver nanoparticles prepared by this method are free from any metal ions contamination, and are suitable for use in semiconductor industry.
