Abstract
The present study highlights the green synthesis of silver nanoparticles (Ag NPs) using an eco-friendly, cost-effective, and sustainable green synthesis route. Silver nitrate (AgNO₃) was utilized as a precursor, while Crotalaria juncea L. (Sunn Hemp) plant extract acted as a natural reducing and stabilizing agent. Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray Spectroscopy (EDS) revealed nearly a granular texture of nanoparticles with slight agglomeration and confirmed the elemental composition of strong silver peak with exceeded 85–95 wt%, and other minor peaks (for C and O) may be observed due to capping agents or residual organic biomolecules. The X-ray diffraction (XRD) analysis confirmed the formation of a sharp peaks that match the face-centered cubic (fcc) phase of Ag with an average crystallite size ranging ~30–55 nm. Fourier Transform Infrared Spectroscopy (FTIR) indicated the presence of bioactive functional groups responsible for the capping and stabilization of the nanoparticles. The appearance of the Ag–O vibration near ~410-420 cm⁻¹ provides direct evidence of AgNP formation. The UV–Visible absorption spectrum displayed a sharp and centered surface plasmon resonance (SPR) peak at around ~415-420 nm validating the formation of Ag nanoparticles. The synthesized Ag NPs exhibited excellent purity, stability, and homogeneity, underscoring their potential applications as a nanofertilizer formulations for sustainable agricultural development.
