Abstract
This research work presents a facile and green route for synthesis silver sulfide (Ag<sub>2</sub>SNPs) nanoparticles from silver nitrate (AgNO<sub>3</sub>) and sodium sulfide nonahydrate (Na<sub>2</sub>S.9H<sub>2</sub>O) in the presence of <em>rosemary</em> leaves aqueous extract at ambient temperature (27 <sup>o</sup>C). Structural and morphological properties of Ag<sub>2</sub>SNPs nanoparticles were analyzed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The surface Plasmon resonance for Ag<sub>2</sub>SNPs was obtained around 355 nm. Ag<sub>2</sub>SNPs was spherical in shape with an effective diameter size of 14 nm. Our novel approach represents a promising and effective method to large scale synthesis of eco-friendly antibacterial activity silver sulfide nanoparticles.
