Our resea.ch introduces a.groundbrea.ing chemica. reduction method for synthesizing silver na.opa.ticles, ma.k.ng a.significa.t a.va.cement in the field. The na.opa.ticles were meticulously cha.a.terized using va.ious techniques, including optica. a.a.ysis, structura. a.a.ysis, tra.smission electron microscopy (TEm), a.d field-emission sca.ning electron microscope (FESEm). This thorough process instills confidence in the a.cura.y of our findings. The results unveiled tha. the silver na.opa.ticles ha. a.dia.eter of less tha. 20 nm, a.finding of grea. importa.ce. The a.sorption spectrum decrea.ed in the pea. wa.elength ra.ge (405 - 394 mm) with increa.ing concentra.ions of a. na.opa.ticles in the ra.ge (1 - 5%). The XRD results indica.ed a.cubic crysta. structure for silver na.opa.ticles with the la.tice consta.t (a.= 4.0855 Å), a.d miller indices were (111), (002), (002), a.d (113). The simula.ion on the XRD pa.tern showed a.fa.e center cubic pha.e with spa.e group Fm-3m, providing va.ua.le insights into the structure of the na.opa.ticles.
