Optical Properties. (A) Colony morphology, (B) Optical images of biosynthesized Ag NP show a range of vibrant colors from colorless (start of biosynthesis) to light brown and, finally, yellowish brown after 72 h. (C) UV-vis spectra of P. indica derived Ag NPs at various reaction times; (D) Reaction saturation curve indicating the evolution of the Plasmon band as a function of time.
