Abstract :
This study successfully prepared highly concentrated and stable suspensions of silver nanoparticles using an organic base, triethylamine, as the promoter and 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 are stabilized by excess triethylamine. The suspensions of silver nanoparticles prepared by this method are free from any metal ions contamination, and are suitable for use in semiconductor industry.
