| Abstract: | Au nanoparticles dispersed ZrO2 thin films were prepared from two precursors HAuCl4·4H2O and ZrOCl2·8H2O in air. The structural properties and size of Au particle in ZrO2 film were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The surface analysis with atomic force microscopy (AFM) showed the effect of monoethanolamine on preventing the migration of Au particles to the surface. The absorption peak of Au particles by the surface plasma resonance was observed and the red shift of absorption peak was discussed. |
