In the present work, AgNPs were prepared through chemical reduction method by varying the reducing agent concentration. Trisodium citrate (Na3C6H5O7) is used as reducing agent and PVA as capping agent. X-ray diffractometer (XRD) results showed that as reducing agent concentration increased, the average crystallite size decreased. FESEM results elicited decrement of particle size with increase of reducing agent concentration. EDS analysis confirmed the pure elemental silver formation. FTIR spectrum emphasized the intact of PVA with AgNPs. Photoluminescence studies revealed the enhancement in intensity with increase of reducing agent concentration due to decrease of particle size.
