Effects of pH on Tin Nanoparticles Prepared Using a Modified Polyol Synthesis

Abstract:

The effects of pH on the morphology and size distribution of Sn nanoparticles (NPs)synthesized using a modified polyol method were investigated. An ammonia solution wasused to increase the pH, and at pHvalues ranging from 10.3 to 12, the average size and size deviation of thesynthesized Sn NPs decreased with increasing pH. We believe that higherpH enhances the rate of reduction of Sn ions during the synthesis, resulting inan increase in nucleation. Therefore, theconcurrent formation of many nuclei might be the main cause for the reduction inaverage particle size and for the enhancement in size uniformity.
