ANALYSIS OF THE OPTICAL PROPERTIES OF SILVER NANOPARTICLES SYNTHESIZED USING AMARANTHUS EXTRACTS

M. Jannathul Firdhouse and P. Lalitha*

Optical properties of metal nanomaterials hold both fundamental and practical significance. Nanosilver exhibits fascinating optical properties directly related to the Surface Plasmon Resonance(SPR) which corres-ponds to the shape and size distribution of the particles. UV-Visible spectral measurements are useful in predicting the size of nanosilver. Optical response of nanoparticles makes them potentially useful for nanoscopic sensors, biological labels and electronics. The present study deals with the biogenic synthesis of silver nanoparticles using Amaranthus leaf extract and studying its optical properties in a UV-Visible spectrophotometer. The results of the study clearly shows that the concentration of the capping molecule to be responsible for the shape and particle size dis-tribution of silver nanoparticles.
