In this study, silver nanoparticles were prepared through polyol process. To increase the concentration of silver nanoparticle, effects of solvent, silver salt, and polyvinylpyrrolidone (PVP) on the reduction were investigated. The solvent effect was verified by using different solvents (ethanol, ethylene glycol, and glycerol). As the hydroxyl group in the solvent increased, the reduction ability also increased. Silver nitrate (AgNO3), silver tetrafluoroborate (AgBF4), silver fluoride (AgF), and silver perchlorate (AgClO4) were employed as a precursor. According to the kind of silver salt, color of colloid was different. It is expected that the pH depending on the silver salt solution affected its reduction. Also, the effects of molecular weight and amount of PVP as a stabilizer and reducing agent were studied. The degree of reduction was measured by using UV-vis spectrophotometer and silver ion selective electrode (ISE). The particle size was analyzed with dynamic light scattering (DLS) and transmission electron microscopy (TEM).
