Abstract

In this paper, we report fabrication and characterization of ZnO/Ag and ZnO/Au core/shell nanocomposites by 2-hour laser irradiation of the two solutions first containing mixture of ZnO and Ag nanoparticles and second containing ZnO and Au nanoparticles. The process of fabrication was carried out by Nd:YAG second harmonic pulsed laser and the prepared samples were characterized by UV–visible absorption spectroscopy, transmission electron microscopy (TEM), and photoluminescence measurement (PL). It was found that the thickness of the shell layer around the core can be controlled by laser irradiation time.
