In this work, polyvinylpyrrolidone(PVP)-capped silver nanoparticles were synthesized using ethylene
glycol as solvent and reducing agent through a simple, one-pot solvothermal method at 160 C. UV–vis
spectroscopy, TEM and Raman spectra are used to characterize the PVP-capped silver nanoparticles.
The results show that the formed silver nanoparticles are anisotropy with different size and morphology
such as triangle, hexagon and pentagon. Moreover, the formation process of silver nanoparticles was discussed
in detail. Furthermore, the formed silver nanoparticles displayed high surface-enhanced Raman
scattering effects.
