Resumen:
This research proposes a method to obtain Au nanoparticles (NPs) at a ZnO/SiO2 interface. Initially a well defined Au thin film was grew between of ZnO film and SiO2 glass layers. Post-treatment of 10 MeV Si3+ irradiation or/and thermal annealing treatments were used. Samples were analyzed by Optical Absorption Spectroscopy, Rutherford Backscattering Spectrometry, X-Ray Diffraction and Transmission Electron Microscopy. Results showed the pulverization of initial Au thin film and the formation of NPs in both sides of ZnO/SiO2 interface and in between. In general the formations of Au NPs sizes inside both matrices were between 3 and 8 nm. Last thermal treatment was important because caused the ZnO film recovery from irradiation damage. © 2013 Elsevier B.V. All rights reserved.
