Micro Structural Parameters of Silver Nano Particles Using Whole Pattern Fitting Technique

Abstract

Silver Nano particles are synthesized by Conventional method of biosynthesis of silver nano particles using extract of Parthenium hysterophorus. The synthesized Nano particles were subjected to XRD and SEM analysis for the characterization process for estimating the size of crystalline particle and figure out the morphology. The as-prepared powders are all nano-sized ( nm) and the same is confirmed by broadening of the X-ray diffraction peaks and Scanning electron microscopy. XRD results show that Crystallite area decreases with increasing concentration. The crystallite size (<N>), lattice strain (g in %), stacking faults (αd) and twin faults (β) determined by whole powder pattern fitting technique, developed by us.We have studied the microcrystalline parameters from XRD. Activation energy has been computed for these systems.
