“…Non-uniformities in the lattice, such as faulting, dislocations, antiphase domain borders, and grain surface relaxation all contribute to the lattice strain, as shown in Table . Using the Williamson–Hall eq , − we may determine the crystallite size and lattice strain. Peak broadening in the diffraction pattern because of experimental errors can be calculated using the following formula. β 0.25em cos nobreak0em.25em⁡ θ = 0.25em 0.89 D + 4 ε 0.25em sin nobreak0em.25em⁡ θ where β is the full width at half-maximum, ε is the lattice strain, D is the average crystallite size, θ is Bragg’s diffraction angle, and the radiation wavelength λ = 0.154056 nm.…”

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.
