Silver and gold ions, in poly (vinyl alcohol) (PVA) and Isopropylachol have been reduced by electron beam irradiation to produce Ag and Au clusters as nanoparticles in fully reduced and highly pure state. XRD (X-ray diffraction) technique confirmed the zero valent state of silver and gold. UV-visible absorption spectral characteristics of Ag and Au clusters obtained under different irradiation dose, Metal Precursor, isopropylacohol(IPA), poly (vinyl alcohol) (PVA) concentration. TEM(Transmission electron microscopy) of the nanocomposite films revealed the presence of Ag and Au particles with diameter and shape in PVA matrix. |
