Abstract
Presently, the green synthesis method of nanomaterials is well-recognized due to its inexpensive and environmentally friendly route. Silver nanoparticles (AgNPs) synthesized by the green synthesis method is suitable to manipulate the light interaction by inducing the surface plasmon resonance (SPR). Therefore, AgNPs demanded their potential application in plasmonic devices. This paper reports the green synthesis of AgNPs and the investigation of their properties. X-ray diffraction (XRD) study endorsed the presence of pure Ag phases with its face-centered cubic structure. The ultraviolet–visible (UV–vis) spectroscopy analysis evidenced the absorption peak at wavelength 420 nm, which is attributed to the induced surface plasmon resonance (SPR). Fourier transform infrared spectroscopy (FTIR), and Raman studies demonstrated the various vibration peaks concerning the elements present in the green synthesized AgNPs. The preparation of spherical Ag nanoparticles with their diameter from 24 to 49 nm is investigated by scanning electron (SEM) measurement. The energy-dispersive X-ray spectroscopy (EDAX) investigation endorsed the dominant peaks of Ag. Finally, the AgNPs used as the catalyst for the photodegradation study of Rhodamine B dye and the result is explored.
