Abstract
In this study, synthesis and characterizing of Gold:Zinc Oxide (Au:ZnO) as a core:shell nanoparticles (CSNPs) has been prepared via Laser Ablation at various Laser Pulses Energy 400, 600, and 800 mJ with 200 strokes. Further confirmation of the production of Au:ZnO CSNPs by analyzing the structural and optical properties from aggregated Au:ZnO. CSNPs obtained via drop casting Au:ZnO CSNPs colloidal solutions into silicon wafers. Nanoparticles were identified via X-ray diffraction, transmission electron microscopy, Fourier transform infrared, and ultraviolet–visible absorption spectrum. It was found particle size increased with energy, and the shell of ZnO on the surface of gold nanoparticles is strongly affected on absorptions, while the absorption of Au:ZnO CSNPs decreased when the decorated surface of Au by ZnO corresponding to Au and ZnO as an individual.
