Surface plasmon resonance study of Ag nanoparticles colloidal

الملخص EN

Silver nanoparticles (Ag-NPs) have been prepared using the electro-chemical method.

The experimental setup of this technique consist of two electrodes of pure silver (99.2 %), the applied voltage on the electrodes is 20 V and the current through the colloidal was about 0.4 Amp.

The silver nanoparticles crystallization has been studied; the crystalline structure appears Face center Cubic.

The optical properties of silver nanoparticles are strongly affected by the Local Surface Plasmon Resonance (LSPR).

The wavelength of maximum absorption band for an Ag NPs have a range (~350nm-550nm).
