Spatial Variation of Local Field by the Ag Nanoparticle on the PANI Matrix: A Non Linear Optics (NLO) Perspective

The Ag-PANI nanocomposite was prepared using wet chemical synthesis method. The morphological and optical characterization studies were carried out using FE-SEM and UV-Visible spectrophotometer. The FTIR band peaks confirmed the presence of the polyaniline in the Ag-PANI nanocomposites. Variation of the optical characteristics of the Ag-PANI nanocomposites was studied while adding the PVA and acetonitrile. The non linear optical behaviour of Ag-PANI nanocomposite material was studied using the Z-scan measurement technique.
