【 摘 要 】

Herein, we report a simple greensynthesis of silver nanoparticles (Ag NPs) by the reduction of aqueous silversalt solution using leaf broth of Eucalyptus camaldulensis. The profileof synthesized silver nanoparticles was evaluated by using UV-visible spectrophotometer,X-ray diffractometer, atomic force microscope, energy-dispersive X-rayspectroscope and scanning electron microscope. Surface plasmon resonance peakof silver nanoparticles appeared at 425 nm in UV-vis spectra of silver nanoparticles.XRD studies clearly confirmed the crystalline nature of the synthesized nanoparticles.The EDX analysis disclosed the arranged inorganic composition of the synthesizedAg NPs. Atomic force microscopy investigation revealed 3D surface profile ofnanoparticles. From the SEM images, the silver nanoparticles were found to bemore or less spherical with an average diameter range of 110-250 nanometers.
