摘要：
Silver nanoparticles embedded in polyvinyl alcohol (6.2 nm in size) were synthesized by simple polyol process. Silver nanoparticles were deposited on glass plates by dip coating method and exposed to DC glow discharge plasma for 10 minutes and 60 minutes. Samples were characterized by UV-Vis absorption spectra, energy dispersive x-ray spectrogram (EDX), scanning electron microscopy (SEM), a n d transmission electron microscopy (TEM). UV- Vis spectrum showed a single peak at 415 nm due to the surface plasmon resonance (SPR) of silver nanoparticles embedded in polyvinyl alcohol. Position of surface plasmon resonance (SPR) peak changed after the samples were exposed to DC glow discharge plasma, which reveals that the DC glow discharge plasma can be used as a size controlling agent for the silver nanoparticles embedded in polyvinyl alcohol.
