Abstract

Stable and uniformly dispersive silver nanoparticles were prepared though reducing silver nitrate with polyvinylpyrrolidone. The effects of preparing conditions on the stability of silver nanoparticles were investigated. The results showed that the surface plasmon resonance (SPR) band of the silver nanoparticles was about 403nm. The silver nanoparticles remained stable for more than one month. Water, alkali solution and glucose could accelerate the reaction. The stability of the silver nanoparticles was increased by adding glucose.
