In this cutting-edge research era, silver nanoparticles
impose a substantial impact because of their wide applicability in
the field of engineering, science, and industry. Regarding the vast
applications of silver nanoparticles, in this study, the crystallographic
characteristics and nanostructures of silver nanoparticles extracted
from natural resources have been studied. First, biosynthetic silver
nanoparticles were synthesized using the Pathor Kuchi leaf (PKL) extract
as a mediator, and their crystal structures and characteristics were
analyzed by UV–visible absorption spectroscopy, Fourier transform
infrared (FTIR) spectroscopy, X-ray diffraction (XRD), field-emission
scanning electron microscopy (FESEM), and energy-dispersive X-ray
(EDX) analysis. The average crystallite size of the synthesized silver
nanoparticle was determined to be 20.26 nm, and also the lattice strain,
intrinsic stress, and dislocation density were measured to be 2.19
× 10–3, 0.08235 GPa, and 3.062045 × 10–3/nm2, respectively. Further, the prepared
sample of silver nanoparticles shows four peaks in the X-ray diffraction
pattern, which correspond to the (111), (200), (220), and (311) face-centered
cubic (FCC) crystalline planes. The outstanding finding of this work
was that when the lattice parameters of the precursor were increased,
the volume of the material did not considerably change, but the particle
size decreased. Second, it was clearly demonstrated that this straightforward
method is a clean, cost-effective, environmentally sustainable, nontoxic,
and efficient route for the synthesis of silver nanoparticles (Ag
NPs) using PKL leaf at ambient temperature, which also satisfies the
green chemistry requirements. Finally, this study demonstrates the
scope for the production of silver nanoparticles using low-cost natural
resources.
