Herein, the electric and magnetic responses of the ZnO nanomaterial are enhanced by introducing gold into ZnO to form Au-ZnO core–shell nanomaterial. The ZnO nanostructures are studied by optimizing their particle size in the near-infrared and far-field frequency region using Mie theory. The intense light scattering peaks with a peak shift for the Au-ZnO core–shell nanomaterial at the optimized particle size and particular wavelength in the near-infrared region are observed. A strong electric and magnetic pattern for the Au-ZnO core–shell nanomaterial is observed in the near-infrared and far-field frequency region as compared to the ZnO nanoparticles due to the surface plasmon property of the gold.
