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 was used to increase the pH, and at pH values ranging from 10.3 to 12, the average size and size deviation of the synthesized Sn NPs decreased with increasing pH. We believe that higher pH enhances the rate of reduction of Sn ions during the synthesis, resulting in an increase in nucleation. Therefore, the concurrent formation of many nuclei might be the main cause for the reduction in average particle size and for the enhancement in size uniformity.
