Synthetic technology of nanomaterials through plant extract is integrating due to its simplicity and also requires less apparatus. Recent development records the green synthesis of nanoparticles using the biological reduction method with the help of plant extracts. The unique process of developing an environmental friendly way for the synthesis of nanoparticles brings the significant step in the wide field of nanotechnology. Syntheses of silver nanoparticles (AgNps) are carried out by complete reduction of silver nitrate using Achras sapota, Psidium guajava, and Azadirachta indica plant extracts. The structure, morphology, and bonding nature of as-synthesized AgNps have been studied by X-ray diffraction (XRD), scanning electron micrograph (SEM), and Fourier-transform infrared (FT-IR) tools respectively. The presence of the silver metal in the sample was confirmed by EDX pattern. Thermal study of the prepared AgNps is undertaken to know its thermal behavior.
