In this paper, the possibility of encapsulating Au metallic nanoparticles (MNPs) non-epitaxially in a semiconducting and insulating shell was tested in order to explore their potential application in photovoltaic thin films. The proposed synthesis of growing Ag onto Au, doping it with sulfur and ion exchanging the Ag with Zn or Cd was shown to be successful through Transmission Electron Microscopy (TEM) and UV/VIS spectra. The final products of the synthesis showed a ~50 – 100nm red shift of the Au MNP plasmon peak from its benchmark wavelength of ~525nm.
