Ultrafine transition metal nanoscale materials have considerable attention due to their unique property. Silver nanoparticle (AgNP) is one of the more gorgeous because of its uses in various fields such as catalysis, sensors, photonics, solar cell and pharmaceuticals. Various physical, chemical and mechanical methods are available for synthesis of nanomaterials. However all the above methods are consuming more energy, toxic chemical and lengthy process. In the field of nanotechnology researcher are looking for natural systems to synthesize the nanomaterials in order to develop the environmental safe green process. The utilization of biological systems has the enormous benefits in the synthesis of nanomaterials. In this present study a facile methods is explored to prepare stable AgNPs by using Peltophorum pterocarpum (PP) flower extract as reducing and capping agent and aqueous silver nitrate as metal precursor. The use of plant extract for the synthesis of nanoparticles have advantages over microorganisms due to long process and cell cultural maintenance. AgNPs have been synthesized by adding different dosage of PP flower extract into the aqueous silver nitrate (0.001 M) solution. Instantaneously, the colour less solution was turned to brownindicating the formation of AgNPs. The synthesized nanoparticles are characterized by Ultra Violet – Visible spectrum (UV-Vis), High Resolution Transmission Electron Microscopy (HR-TEM), X-Ray diffraction and Fourier Transform Infra Red spectroscopy (FT-IR). HR-TEM image shows the nanostructures of prepared AgNPs. The UV-Vis spectrum shows an absorption peak around 420nm. The FWHM of the UV-Vis spectrum varies depend on the dosage of flower extracts. The XRD reveals that the prepared silver nanoparticles have crystalline nature.
