Comparison of Optical and Morphological Analysis of Chemically Synthesized Silver Nanoparticles using Nucleation and Growth method

Abstract

The aim of this study is to do the optical and morphological analysis of chemically synthesized silver nanopar-ticles using nucleation and growth methods as compared with size and absorbance. Chemically synthesized silver nanoparticles were synthesized by silver nitrate with sodium borohydride (N aBH4) in the presence of sodium citrate as capping agent. Here seven groups were analyzed and the total sample size was 26. The nanoparticle was characterized by the means of UV Visible (UV-Vis) spectroscopy and scanning and electron microscopy (SEM).The absorbance and morphology is analysed of the samples. Nanoparticles are having different absorbances in different wavelengths. It is very essential to analyse the absorbance of the nanoparticles. The particle was analysed from 200–700 nm. It has high absorbance in the visible region about 400–420 nm which is in the violet region. The morphology is analysed using SEM to determine the size distribution. It has an average size of 9.5 nm. The morphology (SEM) is taken to analyse the size distribution of the particle.
