Synthesis of Silver Nanoparticles by a Sonochemistry Method Useful for Two-Dimentional Nanoparticle Arrays
Silver nanoparticles were synthesized by a sonochemistry method by using silver stearate and triphenylphosphine as silver precursor and reduction accelerator respectively. The experimental conditions that influence the formation and organization of the particles were investigated, and the particles were characterized by TEM. Results showed that well-ordered two-dimentional (2D)-monolayer was formed after solvent evaporation on a carbon-coated copper TEM grid at the optimal experimental conditions which was that the mole percentage of the amount of reducing agent and triphenylphosphine to silver precursor was 10% and 50% respectively, and the ultrasound power was set at 60% (relative to the maximum ultrasound power value of the machine).
