Analysis of Crystallographic Structures and Properties of Silver Nanoparticles Synthesized Using PKL Extract and Nanoscale Characterization Techniques

In this cutting-edge research era, silver nanoparticlesimpose a substantial impact because of their wide applicability inthe field of engineering, science, and industry. Regarding the vastapplications of silver nanoparticles, in this study, the crystallographiccharacteristics and nanostructures of silver nanoparticles extractedfrom natural resources have been studied. First, biosynthetic silvernanoparticles were synthesized using the Pathor Kuchi leaf (PKL) extractas a mediator, and their crystal structures and characteristics wereanalyzed by UV-visible absorption spectroscopy, Fourier transforminfrared (FTIR) spectroscopy, X-ray diffraction (XRD), field-emissionscanning electron microscopy (FESEM), and energy-dispersive X-ray(EDX) analysis. The average crystallite size of the synthesized silvernanoparticle was determined to be 20.26 nm, and also the lattice strain,intrinsic stress, and dislocation density were measured to be 2.19x 10(-3), 0.08235 GPa, and 3.062045 x 10(-3)/nm(2), respectively. Further, the preparedsample of silver nanoparticles shows four peaks in the X-ray diffractionpattern, which correspond to the (111), (200), (220), and (311) face-centeredcubic (FCC) crystalline planes. The outstanding finding of this workwas that when the lattice parameters of the precursor were increased,the volume of the material did not considerably change, but the particlesize decreased. Second, it was clearly demonstrated that this straightforwardmethod is a clean, cost-effective, environmentally sustainable, nontoxic,and efficient route for the synthesis of silver nanoparticles (AgNPs) using PKL leaf at ambient temperature, which also satisfies thegreen chemistry requirements. Finally, this study demonstrates thescope for the production of silver nanoparticles using low-cost naturalresources.
