This paper describes a simple and convenient procedure based on the Tollens process for preparation of silver nanoparticles with relatively narrow distribution in size. The starting reagents were similar to those commonly used electroless deposition silver. Only under appropriate conditions, mixing these was able generate stable aqueous dispersions colloids rather than thin films deposited surfaces objects immersed plating solution (including interior surface container). We have demonstrated capability feasibility this approach by forming dimensions range 20–50 nm. These could exist as very water, or submonolayer coating microscale colloids. also explored use light scattering simulation study oxidation (by air) nanoparticles.
